Chapter 3 Notes

P

3.1 LAN Environment Notes

• The ETERNUS Disk storage system can be connected to a server via an existing LAN. However, a decrease in LAN performance may be observed by prior users of said LAN.

• For the iSCSI LAN (used to transfer data), do not set multipath configuration with IP Network Multipathing (IPMP).

• As with an FC-SAN, because of the large data flows (traffic volumes) the iSCSI LAN is assumed to be a dedicated LAN separate from the business and management LANs, and constructed with its own LAN switch.

• For IP network security reasons too, it is useful to separate the iSCSI LAN (for data transfers) and management LAN (for administration) to prevent cross-access between them (use of VLAN to separate the LAN segments is recommended).

• A configuration where multiple LAN ports of a single server are connected to the same network may be restricted depending on the OS and/or driver specifications. For a multipath connection, connect each path using different LAN segments by separating the VLAN and so on.



3AM-4182-03ENZ0

Chapter 3 Notes > 3.2 Server Startup and Power Supply Control Notes

P

Example LAN switch connection configuration

*1: In this system configuration, multipaths provide redundant connections between the servers andstorage system. LAN switches #1 and #2 provide physical separation of the network paths.

*2: A separate LAN segment is provided in the LAN switch (using the switch VLAN function) for eachgrouping of business servers and disk storage systems (equivalent to the FC zones).

3.2 Server Startup and Power Supply Control Notes

Before turning the server on, check that the ETERNUS Disk storage systems and LAN switchesare all "Ready". If the server is turned on and they are not "Ready", the server will not be able torecognize the ETERNUS Disk storage systems.Also, when the ETERNUS Disk storage system power supply is being controlled by a con-nected server, make sure that the ETERNUS Disk storage system does not shut down beforethe connected servers. Similarly, the LAN switches must also be turned off after the connectedservers have been shut down. If turned off, data writes from the running server cannot be saved to the ETERNUS Disk storagesystems, and already saved data may also be affected.

The iSCSI LAN and managementLAN segments are kept separatein the iSCSI LAN switches, helpingmaintain the security of each.

Similarly to FC-SAN, adedicated LAN is used foriSCSI, not the business LAN.

Chapter 4 Checking the Server Information

P

The server information registered in the ETERNUS Disk storage system should be checked.A variety of commands are used to check the following server information.

• iSCSI Software InitiatorSince iSCSI Software Initiator is provided with the OS, installation is not required.Check the SUNWiscsiu and SUNWiscsir packages using the "pkginfo" command.

• iSCSI Initiator nameExecute the following command:

The iSCSI Initiator name is displayed in the "Initiator node name" column.

• Server-side LAN card IP address for connecting to the ETERNUS Disk storage systemExecute the following command:

Set this IP address if it is not already set.

• Initiator CHAP NameThe Initiator CHAP Name is the user name for unidirectional CHAP authentication, and is notrequired if CHAP authentication is not used.Execute the following command:

The Initiator CHAP Name is displayed in the "CHAP Name" column of the applicable targetinformation.

# iscsiadm list initiator-node

# ifconfig -a

# iscsiadm list initiator-node

7.2.1 Setting Up the Command Queue Depth

Set the number of commands allowed to be queued (command queue depth) on each LUN in theETERNUS Disk storage systems from the LAN card. This setting optimizes the connectionbetween the ETERNUS Disk storage systems and the server.

Procedure

1 Edit the configuration file.Edit the configuration file (/etc/system) and specify the command queue depth.

The appropriate "ssd_max_throttle" parameter value is determined by the ETERNUS Diskstorage system model, as follows:

The parameter to be specified is determined by the CPU which is installed in the server tobe connected.

• For SPARC

Specify the command queue depth for the "ssd_max_throttle" parameter.Add this parameter if it does not exist.

• For x86

Specify the command queue depth for the "sd_max_throttle" parameter.Add this parameter if it does not exist.

2 After editing the configuration file, save it.

3 After the setting is complete, check the configuration file for incorrect settings.

4 Reboot the server.

7.2.3 Server Settings when CHAP Authentication is Used

The following operations are required for CHAP authentication.

• Setting the Initiator secret (password setting to connect to the ETERNUS Disk storage system)

• Setting the Initiator CHAP Name (CHAP name setting to connect to the ETERNUS Disk storage system)

• Enabling CHAP

Procedure

1 Set the Initiator secret.This is a password that must be set so that the Initiator can connect to the targetETERNUS Disk storage system. The CHAP secret set here must match that set in Targetinformation.

Example:To set the password "initiator000"

2 Set the Initiator CHAP Name.The Initiator Node Name is the default Initiator CHAP Name. Use the "iscsiadm" commandto set a new Initiator CHAP Name. The Initiator CHAP Name set here must match that setin Target information.

Example:To set "initiator" as the CHAP Name

Passwords are restricted to a maximum of 16 characters by theSolaris operating system. For 17 or more characters, the followingmessage is output:

# iscsiadm modify initiator-node --CHAP-secretEnter secret:initiator000Re-enter secret:initiator000

P

9.1 Enabling MPxIO

Enable MPxIO.Check the [mpxio-disable="no"] line in the "/kernel/drv/iscsi.conf" file.Change the parameter to "no" when "yes" is set.

Example for changing the "/kernel/drv/iscsi.conf" file:

9.2 Reconfiguring and Restarting the Server

Reconfigure and restart the server to effect the new settings.

Use the "format" command to check the MPxIO multipath status after multipathing is set up.

For the iSCSI LAN (used to transfer data), do not set mult ipathconfiguration with IP Network Multipathing (IPMP).When configuring the multipath, use MPxIO in the same way as FC-SAN isused for configuration.

# To globally enable MPxIO on all iscsi ports set:# mpxio-disable="no";## To globally disable MPxIO on all iscsi ports set:# mpxio-disable="yes";#mpxio-disable="no"; <- Check that �no� is set.
