HP Command View EVAPerf does not display virtual disk and disk g roup

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 EVAPerf 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

LUN presenta

tions from the storage system. The s ituation occurs because VCS does not change the SCSI

inquiry stri

ng 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 EVAPerf is run on a host that never had LUN presentations from

the storag

e system. Typically, HP Command View EVAPerf is run on a manag ement server which

will not ha

ve I/Os to the storag e system. In this conﬁguration, the management server does not

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