8x00 Enterprise Virtual Array release notes (XCS 6.220) (5697-8035, April 2009)

• You can bypass this issue by setting the load balancing policy for each LUN to NLB using the

MPIO DSM CLI.

Microsoft is currently working on a resolution to address this issue.

C-series switch settings for XCS 6.100 or later

If C-series switches are not set correctly, the EVA host ports may not log back in to the fabric after

changes occur in the fabric. This issue involves the following C-series switch model families: 90xx,

91xx, 92xx, and 95xx.

If the switch does not log into the array, disconnect and then reconnect the FC cable on the array or

the switch.

If the above recommendations do not correct the problem, it will be necessary to restart the controller

to restore host port operation. You only need to restart the controller experiencing the host port problem.

This can be done from HP Command View EVA as follows:

1. Open HP Command View EVA and click the icon of the appropriate storage system. You can

select either an initialized or unintialized storage system.

2. On the Initialized Storage System Properties page, click Shut down.

3. Under Controller Shutdown, select the appropriate controller (A or B) for restart.

4. Click Restart.

The controller is restarted. After the restart, the host port should be operating normally.

NOTE:

If HP Command View EVA cannot be used to restart the storage system, use the controller operator

control panel (OCP). The Restart option is located under the Shutdown Options menu on the OCP.

Powering off storage system components

Individual EVA storage array components should not be powered off during normal operation. Before

powering off any storage system component, contact your HP-authorized service representative for

assistance.

Changing storage system cable connections on a C-series switch

If it becomes necessary to move the storage system Fibre Channel cable to a different port on a

C-series switch, or to a port on a different C-series switch, the corresponding controller host port will

become unavailable.

If this situation occurs, it will be necessary to restart the controller to restore host port operation. This

can be done from HP Command View EVA as follows:

1. Open HP Command View EVA and click the icon of the appropriate storage system. You can

select either an initialized or unintialized storage system.

2. On the Initialized Storage System Properties page, click Shut down.

3. Under Controller Shutdown, select the appropriate controller (A or B) for restart.
