With IBM Wave for z/VM this changed dramatically – you can now use andcombine z/VM's virtualization with an intuitive and efficient graphical userinterface that supports Point-and-Click as well as Drog-and-Drop to perform systems and virtualization management tasks.

For historical reasons the administration and usage of z/VM was cmd-linebased and 3270 (“green-screen”) skills were required. This was often an inhibitor, specially for new (FIE) customers.

In most environments Linux on System zruns as a guest (aka virtual machines) on top of z/VM.

Due to the fact that Linux supports and exploits differentarchitectures, the entire systems have different characteristics.That means for example different quality of services,levels of 'RAS' and hypervisors, like IBM z/VM (and PR/SM).

Linux is Linux is Linux is …The Linux operating systems, for all the different platformsout there, look and indeed are the same; they share thesame roots and have common source code (kernel.org).

Administrators and system programmers may workusing 3270 terminal emulation or with IBM Wave interchangeably– the configuration and state of IBM Wave can be updated

and re-read from the underlying z/VM system.

For an outside-in view of the z/VM hypervisor or the Linux guests(ie: to get an idea about resources or performance),Linux administrators no longer need system programmer support– or at least much less.

With IBM Wave, system programmers are now able todefer tasks to Linux administrators with limited z/VM skills,due to the 'role' and 'project' concept that IBM Wave provides.

But the initial setup, as well as the maintenance and upgrade of z/VM stillrequires system programmer skills.

Solution Overview (cont.)

IBM Wave for z/VM can be used for day-to-day use of nearly any z/VM. administration task.

Benefits of using IBM Wave for z/VM

• Most actions can be carried out against multiple objects whether they are on a single or multiple LPARs.

• Intelligent icons help the user understand the status of the system and its resources. For example an icon can indicate whether a virtual guest is running, whether it is running a Linux distribution from Suse or Red Hat, or whether it is a CMS guest, a system service machine or a IBM Wave for z/VM internal virtual server.

• Definition and use of functionality types ensures ordered activation and deactivation of z/VM guests. For example, a database server can be brought up followed by a transaction server and a web server with deactivation occurring in the reverse order.

• Ability to broadcast a message to a set of Linux users. This can be finely filtered with the use of custom attributes.

• Intelligent Active Notes (IANs) allow free form text to be associated with an object and displayed during a mouse hover. Initiating an action on the object causes the IAN to pop up.

• At a glance views of overall system storage utilization with the ability to drill down to the volume level for site level administrators and for Linux administrators views of storage groups to which they are uniquely permitted.

• Simplified mechanism of storage assignment and storage management allowing the IBM Wave user to interact with DASD Volumes, DASD Groups and DIRMAINT regions

• Performance view of all managed systems includes current CPU utilization, page and spool space and virtual to real storage ratios. Drill down to the Linux guest level is also supported.

• Generate concise reports for selected objects with the ability to use complex filters and customization.

• Custom attributes and their associated values can be defined and associated with virtual guests. Multiple attributes can be assigned to guests and then used for grouping and filtering in any combination to take action on a set of guests. For example, an attribute called Server Use could be defined with possible values Production, QA, Development.

The GUI Client

The GUI Client must run on an Windows client. It provides a graphic interpretation of the knowledgebase and allows the user to interact with the TVP using Point-and-Click and Drag-and-Drop operations.

The BTS (WAVESRV)

This server can be a physical or virtual one and hosts the application database, web server and BTS (Background Task Scheduler). There is no limitation on the number of TVPs or virtual guests that one BTS server can manage.

The TVP

The Target Virtualization Platform (TVP) represents the hypervisor which hosts the virtual guests. The BTS and the GUI Clients utilize the TVP API to query and perform changes to the TVP and hosted virtual guests.

• Updates with live data

• GUI client gets its information from the IBM Wave database

• Handles requests using worker threads– User worker threads: Responsible for running user-generated BTS Workunits and

Requests. This is a configurable option. To determine the number of User Worker Threads, use the following formula:

<Number of concurrent IBM Wave Users>*2 + <Number of concurrent clone operations>*<maximum of minidisks in a source guest for cloning>

– Internal worker threads: Responsible for running the internal IBM Wave Workunits and Requests such as the periodic tasks. This is not customizable and is determined by the number of z/VM systems managed by the BTS.

IBM Wave utilizes the SMAPI interface in order to mediate requests from the BTS and the GUI Client.

Specific functions executed on the z/VM System using the following Service Machines:

WAVEWRKS

- The Short Service Machine executes various compiled REXX EXECs tointeract with the z/VM environment.

WAVEWRKL

- The Long Service Machine provides an additional thread of execution to run longer scripts or executes some directory manager commands.

WAVEWRKC

- This Cross-System Cloning Service Machine is used to stream minidisks from a source z/VM system to a target z/VM system during cloning actions.

As part of the auto-detection process when adding a new z/VM System to IBM Wave management, these 3 service machines are created and started on the z/VM System automatically.

Planning and Design for SSI cluster

• The WAVESRV Linux system runs only in one SSI member and is defined as a single-configuration virtual machine (USER) which allows to relocate the WAVESRV guest system in the SSI cluster.

• The Wave Service Machines require a different setup. Wave Service Machines need to run in every SSI member that needs to be managed by Wave.

• There are two possible setup scenario’s.

10/9/2015

47

IBM Inside Sales




• The first is to use the same name and definition for the service machines on each member of the SSI cluster.

• This configuration however requires a lot of manual definitions. You need to create Identities for each service machine on each member of the cluster.

10/9/2015

48

IBM Inside Sales




10/9/2015

49

• The second scenario defines different Wave Service Machines with different names on every member of the SSI cluster.

• The advantage is that you do not need to define any identities and let Wave define all the service machines during the Autodetect step.

Planning and Design for Installations with ESM

• If the environment is not protected by RACF or other security facilities, Wave creates all Wave Service Machines in the Autodetect Step automatically.

• In a “protected” environment, those service machines have to be pre-defined and autorized. Wave will then detect them in the Autodetect Step and will skip the creation of the service machines.

• UserID’s need to be pre-defined and access to mini disks need to be granted.

• The first is to use the same name and definition for the service machines on each member of the SSI cluster.

• This configuration however requires a lot of manual definitions. You need to create Identities for each service machine on each member of the cluster.

Pre-installation configuration tasks for z/VM

Before installing the IBM-WAVE for z/VM rpm into the WAVESRV system some

configuration tasks needs to be finished in the following products.

• z/VM System Management API (SMAPI)

• DIRMAINT

• TCP/IP for z/VM

• Performance Toolkit (Optional)

• ESM like RACF

• When IBM Wave for z/VM uses the SMAPI it must authenticate using an existing z/VM virtual machine name and password. The virtual machine used does not need any special privilege classes, and will never be logged on. It simply needs to be defined in the z/VM USER DIRECTORY for authentication purposes.

• The SMAPI authorized users file is named VSMWORK1 AUTHLIST, and it is located in the VMSYS: filepool under the root directory for VSMWORK1 (VMSYS:VSMWORK1.).

• Care needs to be taken when updating this file. The default file that comes with z/VM 6.3 has the following data in it:

DO.NOT.REMOVE DO.NOT.REMOVE

MAINT ALL

ZHCP ALL

• For this system, we simply used the MAINT userid for authorization within IBM Wave. If you would like to add a new userid to the file it is recommended that you copy an existing line, and then only overtype the userid text on the duplicated line.

DIRMAINT

To support IBM Wave for z/VM, the DIRMAINT virtual machine must run with the C and E PRIVCLASSes added to the default of BD and G. The following command will add privclasses C and E to the DIRMAINT virtual machine:

DIRM FOR DIRMAINT PRIV +CE

The new privilege classes will not take effect until the DIRMAINT virtual machine is logged off and logged back on.

DIRMAINT

Since IBM Wave for z/VM will be allocating DASD space it is necessary to configure the DIRMAINT EXTENT CONTROL file before installing IBM Wave for z/VM.

At a minimum you should have one region defined.

When IBM Wave for z/VM is installed, a dummy region of one cylinder will be created as a placeholder for “empty” storage groups.

If you have already updated EXTENT CONTROL to add regions and groups, you may use one of your already allocated regions.

77

DIRMAINT

To double check the region name and volume name you will use during IBM Wave for z/VM install you may want to execute the following commands and see that a return code of zero is returned.

DIRM DASD QUERY REGION LX9220

DIRM DASD QUERY VOLUME LX9220

We used region name and volume name LX9220. You will need to substitute a value for LX9220 that matches information in your EXTENT CONTROL file.

TCP/IP for z/VM

Since IBM Wave for z/VM has the capability to establish 3270 sessions from within the WAVE GUI it is necessary to update the PROFILE TCPIP file for the z/VM TCP/IP stack to authorize two of the WAVE worker

machines to use the obeyfile command.

The PROFILE TCPIP file is by default created on the TCPMAINT virtual machine’s 198 minidisk. Add the following virtual machines to the OBEY section of that file:

OBEY

OPERATOR TCPMAINT MAINT MPROUTE REXECD SNMPD SNMPQE LDAPSRV MAINT630

WAVEWRKS WAVEWRKL

ENDOBEY

79

10/9/2015

TCP/IP for z/VM

You will also want to make sure that the PORT section of your PROFILE TCPIP contains the following uncommented lines:

PORT

20 TCP FTPSERVE NOAUTOLOG ; FTP Server

21 TCP FTPSERVE ; FTP Server

23 TCP INTCLIEN ; TELNET Server

TCP/IP for z/VM

Lastly make sure that the FTPSERVE virtual machine is automatically started by TCPIP. You should see an AUTOLOG section similar to this:

ENDAUTOLOG

After making changes to the PROFILE TCPIP file, you will need to restart your TCPIP virtual machine to pick up these changes.

Performance Toolkit

If the Performance Toolkit is available, then IBM Wave for z/VM will use this feature to display performance information for individual virtual machines.

In order for IBM Wave for z/VM to be able to use Performance Toolkit, the short duration worker machine (WAVEWRKS) needs to be authorized to gather data from Performance Toolkit.

This is accomplished by adding WAVEWRKS to the FCONRMT AUTHORIZ file maintained on the 191 minidisk of the PERFSVM virtual machine.

82

10/9/2015

80

IBM Inside Sales



Performance Toolkit

Update the FCONRMT AUTHORIZ file with the following entry:

WAVEWRKS * DATA CMD

IBM Wave for z/VM general requirements for Performance Toolkit include making sure that the VMCF interface is turned on. This is accomplished by uncommenting the FC MONCOLL VMCF ON statement in the FCONRMT $PROFILE.

83

10/9/2015

81

IBM Inside Sales



Performance Toolkit

It is also necessary for the CP Monitor to be configured for collection of sample records from the processor, storage and user (all) domains. This is accomplished by making certain that the PROFILE EXEC for PERFSVM has the following commands uncommented:

'CP MONITOR SAMPLE ENABLE PROCESSOR'

'CP MONITOR SAMPLE ENABLE STORAGE'

'CP MONITOR SAMPLE ENABLE USER ALL'

84

10/9/2015

Performance Toolkit

These configuration steps are commonly done when setting Performance Toolkit up for general system use.

It is good however to review the FCONRMT PROFILE and PERFSVM PROFILE EXEC to make certain the necessary configuration steps have been completed.

More about Device Pools

235

IBM Wave uses internal z/VM data to retrieve a unique ID for each Real Device.

– This unique ID is made up of the Logical Control Unit ID with other elements

– This unique ID is a unique identification for each device.

Attention Required status

– If any real device was dedicated to z/VM guest on two or more z/VM systems, IBM Wave would raise an Attention Required status for the real devices.

– If this situation is acceptable, the Attention Required Entry can be ignored.

Transfer Real Devices

– Since Device Pools are associated with Real Devices by their Unique ID, all Real Devices with same Unique ID are transferred to the target Device Pool.

It is possible to link a Managed Entity to a Device Pool.

– It is pure meta-data.

– e.g. It is possible to link an OSA Device Pool to a Router Managed Entity. The Network Viewer will display a link between the Device Pool and the Router.

IBM Wave for z/VM

How to create a prototype and golden image

10/9/2015

347

IBM Inside Sales



Create a golden master

• A golden master is a template for a virtual machine (VM) It can also be referred to as a golden image, a master image or a base image. Usually, a golden image is manually installed and clones are created with minimal modifications.

• Using IBM Wave for z/VM, it is possible to create a prototype that will automate the cloning of a golden image. In order to do this, the following should be in place before a clone can be created:

353

10/9/2015

348

IBM Inside Sales




Sufficient storage space (DASD)

Sufficient memory (RAM)

A VSWITCH

A pool of IP addresses connected to the VSWITCH

A fully installed Linux server that has been deactivated

354

10/9/2015

349

IBM Inside Sales




Important: Once you change a Linux server to become an IBM Wave for z/VM prototype, the Linux server you choose will no longer be able to be logged into and therefore will no longer be bootable.

355

10/9/2015

350

IBM Inside Sales




IBM Wave for z/VM has created the concept of an “associated prototype,” which is composed of both a traditional prototype directory entry and an associate z/VM guest with assigned minidisks and an installed guest operating system.

The associated guest is deactivated and has a password set to NOLOG to prevent it from being actively used. Within the IBM Wave for z/VM GUI, the guest is filtered from the z/VM User Groups tab and only visible in the Prototypes tab.

356

10/9/2015

351

IBM Inside Sales




In a non-SSI environment, the z/VM guest icon is grayed out if a member is inactive: active:

In an SSI environment, it is impossible to tell at a glance if a z/VM guest is inactive on all members of the cluster, as the views are generated on a per-member basis. Use the detailed information panel:

357

Once the z/VM guest is deactivated, right click on the icon and select Cloning --> Convert VM User to Prototype.

IBM-Wave for z/VM

Bare-Metal Installation

10/9/2015

370

IBM Inside Sales



What is an IBM Wave for z/VM bare metal install?

• Intuitive and easy to user interface

– Performs the first phase of the installation

– IBM Wave user provides initial parameters, selects Linux repository and launches the installation

• Performs all necessary z/VM specific tasks

– Builds Linux PARMFILE

– Copy over necessary files for launching the installation program

– IPL guest and launch native installation program

377

10/9/2015

371

IBM Inside Sales



What happens?

• IBM Wave stores all the files relevant to a Linux installation on the WAVESRVS (short) service machine.

• This minidisk is automatically created during the first use of a Linux repository for each z/VM system.

• After submitting the bare metal installation request, IBM Wave will punch all necessary files into the target z/VM guest’s reader and IPL the z/VM guest.

• After the z/VM guest has been IPL’d, and the native install has started, IBM Wave will sample the supplied IP address until the SSH port is available
