HP StorageWorks Enterprise Virtual Array 3000/5000 Release Notes VCS V4.007 (5697-6486, July 2007)

• All EVA 4000/6000/8000 storage systems must be running only one version of XCS (5.100

or later).

• If you need to update both VCS and XCS, do not attempt to upgrade both simultaneously.

Complete the upgrade of one family of ﬁrmware before upgrading the other .

• Suspend DR group replication for the duration of the upgrade process on the destination, even if

the intersite links are not available.

A codeload of one controller forces both controllers on a storage system to reboot. If the controller

being upgraded is used as a destination for replication I/O, the source controller logs new I/O while

the destination controller reboots. Complete the ﬁrmware upgrade of the destination and then resume

the replication to allow the controllers to merge. Wa it for the merge to conclude after a code load or

wait three minutes, whichever is longer, before p erforming the code load on any other storage system i n

the relationship.

Disk Resource Pending Timeout for Microsoft Windows cluster con ﬁgurations

If the disk resource count is greater than 8, HP recommends increasing the Pending Timeout parameter

for each disk resource from 180 seconds to 360 seconds. Increasing the timeout value helps maintain

continuous operation of d isk resources across SAN perturbations.

To view an

d set the Pending Timeout parameter:

1. Open the M

icrosoft Cluster Administrator.

2. Select a disk group resource in the left pane.

3. Right click each disk resource in right pane, one at a time, and select Properties.

4. Select th e Advanced tab from the Properties menu.

5. Locate t

he Pending Timeout value and change it to 360.

6. Click OK.

HP Command View EVAPerf does not display virtual disk and disk group

after upgrading

HP Command View EVAPerf issue exists when upgrading an EVA3000 or EVA5000 from VCS 3.x to

VCS 4.x. Following the upgrade, HP Command View EVAPer f will not be able to display VD (virtual disk)

and VDG (Virtual Disk Group) statistics when HP Command View EVAPerf is run on a Windows host with

LU N presentations from the storage system. The situation occurs because VCS does not change the SCSI

inquiry string when ﬁrmware detects that the storage system has LUNs presented to that Windows host.

This situation does not occur on a new EVA3000 or EVA5000 running VCS 4.007, or a 3.x storage

system that is uninitialized before it is upgraded.

The following technique can be used to avoid this situation:

• Ensure that HP Command View EVA Per f is run on a host that n ever had LUN presentatio ns from

the storage system. Typically, H P Command View EVAPerf is run on a ma n agem ent server which

will not have I/Os to the storage system. In this conﬁguration, the m a nagement server does not

have any LUNs presented to it and this issue will not occur.
