Fixed problems


Fixed problems

None This is the first release of the product.

Known problems and limitations

This section identifies known problems and limitations with this release.

Description Workaround

When the host is booted with a path down, reconnecting the path does not automatically enable the dead paths. After enabling the dead paths, the LUNs do not automatically fail back to their PRIMARY SPs. [120427]

Run the following command to enable dead paths. cfgadm c configure c To manually fail back the LUNs to their PRIMARY SPs, run the following step (not OS dependent): luxadm failover primary /dev/rdsk/c#t#d#s2

Disconnecting a host from a storage group, will hang the format command and put STMS in a perpetual trespass mode, thereby creating a large /var/adm/messages file. [209875]

None.

Disconnecting both LCC cables to a single enclosure will put STMS in a perpetual trespass mode, thereby creating a large /var/adm/messages file. [215897]

None.

Navisphere Host Agent and Navisphere Server Utility can not push a host registration command down all paths to the CLARiiON storage system. [208875]

None. Navisphere Host Agent and Navisphere Server Utility are not supported with Sun StorEdge Traffic Manager.

Limitations

Sun StorEdge Traffic Manager and EMC PowerPath cannot co-exist on the same host.

EMC Navisphere Server Utility and EMC Navisphere Host Agent are not supported on hosts running Sun StorEdge Traffic Manager.

Technical notes

Manual registration of Sun StorEdge Traffic Manager hosts

The Navisphere Agent and Navisphere Server Utility are not supported on hosts with Sun StorEdge Traffic Manager. These hosts must be manually registered with CLARiiON storage systems. EMC recommends using the steps below.

Determining host HBA WWNs

Determine the WWN (world wide names -- the embedded, numeric identifier) of each HBA that you will connect to the CLARiiON storage systems. Create the following shell script:

#!/bin/sh

for i in `cfgadm |grep fc-fabric|awk '{print $1}'`;do

dev="`cfgadm -lv $i|grep devices |awk '{print $NF}'`"

wwn="`luxadm -e dump_map $dev |grep 'Host Bus'|awk '{print $4}'`"

echo "$i: $wwn"

done

Sample output of the above script:

c8: 210000e08b105e35

c9: 210100e08b305e35

where c8 and c9 are the HBA controller numbers and 210000e08b105e35 and 210100e08b305e35 are the worldwide port names of the HBAs.

Make a note of each controller number and worldwide port name; you will use these numbers later to complete the manual host registration process.

Technical notes


Using Navisphere Manager

Follow the procedures below if you are managing your storage system with Navisphere Manager.

Setting connection properties using Navisphere Manager 1. Right-click the storage-system name in the Enterprise Storage

window in Navisphere Manager.

2. Click Connectivity Status in the pop-up menu. The Connectivity Status dialog opens.

If the zones are activated and your host system has been booted, you should see the initiator WWNs of your HBAs with a Fibre Logged In status of Yes. You may have to wait for Navisphere Manager to update its initiator table from the storage system, if your system has booted and the zones have been established, and no Fibre Logged In entries are appearing as Yes.

If, after 60 seconds, the storage system still does not show a Yes in the Fibre Logged In column, examine the zoning configuration and status using the fabric switch configuration tool supplied by the switch manufacturer.

Registering the connection using Navisphere Manager When you have established a connection between the SP and the HBA, you must register the connection. The registration process assigns a specific initiator type to the connection between the SP port and the HBA. This initiator type determines how the SP responds to SCSI commands received on the port.

To register the connection:

1. From the Connectivity Status dialog, select the connection for the WWPN of the HBA, and click Register to open the Register Initiator Record dialog.

2. Select the following:

Initiator Type of CLARiiON Open. ArrayCommPath box to enable the correct LUNZ behavior. Unit Serial Number of Array. Failover Mode of 1.

3. In the Host Information box, select New Host or Existing Host and specify the following:

If this is a New Host, enter the hostname and IP address. If this is an Existing Host, click Host, and select the host from

the pull-down list. 4. Click OK.

After a few seconds, the Connectivity Status dialog appears again with the registration status changed from No to Yes.

When you have completed registration for all of your new HBA connections, you are ready to create a storage group and make your LUNs visible to the host.

Using Navisphere Express

Follow the procedures below if you are managing your storage system with Navisphere Express.

Setting connection properties using Navisphere Express 1. Start Navisphere Express.

2. In the navigation pane, under Manage, click Connections to open the Manage Connections page.

If the zones are activated and your host system has been booted, you should see the initiator WWNs of your HBAs with an SP/Port Status of Active[Unregistered]. You may have to wait for Navisphere Express to update its initiator table from the storage system, if your system has booted and the zones have been established, but no SP/Port Status entries are appearing as Active[Unregistered].

If, after 60 seconds, the storage system still does not show Active[Unregistered] in the SP/Port Status column, examine the zoning configuration and status using the fabric switch configuration tool supplied by the switch manufacturer.

Registering the connection using Navisphere Express When you have established a connection between the SP and the HBA, you must register the connection. The registration process assigns a specific server to the connection between the SP port and the HBA.

To register the connection:

1. From the Manage Connections page, select the check box preceding the server connections you want to register (Active[Unregistered] status), and click Modify.

The Modify Connection page appears.

Technical notes


2. Select the server in which the HBA resides.

If the HBA is in a new server, select New and then enter the name and IP address for the server.

If the HBA is in an already installed server, click Existing, and then select a server from the drop-down list.

3. Click Apply to save any changes.

After a few seconds, the Manage Connections screen appears again with the registration status changed from Active[Unregistered] to Active.

When you have completed registration for all of your new HBA connections, you are ready to create Virtual Disks and make them visible to the host.
