8x00 Enterprise Virtual Array release notes (XCS 6.110) (5697-7469, April 2008)

Powering off storage system c omponents

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

powering off any storage system component, co ntact your H P-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 d ifferent C-series switch, the corresponding controller host por t 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 c onclusion of the restart the h ost port should be operating normally.

C-Series MDS 9020 switch and HP Continuous Access EVA

The C-Seri

es M DS 9020 switch is only suppor ted with HP Continuous Access EVA when the EVA is

running XCS 6.000 or later.

Microsoft Windows MPIO/DSM 2.01.00 is recommended

HP recommends that you upgrade to Windows MPIO/DSM (Device Speciﬁc Module) version 2.01.00,

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

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

prox ied read requests. The minimum supported version is 2 .00.02.

You can download MPIO/DSM 2.01.00 or 2.00.02 from the following website:
