8x00 Enterprise Virtual Array release notes (XCS 6.200) (5697-0024, May 2009)

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 post 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.

4. Click Restart.

The controller is restarted. At the conclusion of the restart the host port should be operating

normally.

C-Series MDS 9020 switch and HP Continuous Access EVA

The C-Series MDS 9020 switch is only supported with HP Continuous Access EVA when the EVA is

running XCS 6.000 or later.

Microsoft Windows MPIO/DSM 3.00.00 is recommended

HP recommends that you upgrade to Windows MPIO/DSM (Device Specific Module) version 3.00.00,

which provides the read optimization feature, for XCS 6.100 or later. The read optimization feature

enables all read requests to be sent to one controller and avoids potential performance impacts due

to proxied read requests. The minimum supported version is 2.00.02.

You can download MPIO/DSM 3.00.00 from the following website:

http://h18006.www1.hp.com/products/sanworks/multipathoptions/index.html

2. Under Browse by OS, select Microsoft Windows.

3. Under FREE Integrations, select Multi-Pathing IO (MPIO) Device Specific Modules.

4. Select Windows MPIO DSM for EVA.

5. Select the appropriate Windows operating system.
