EVAPerf does not display Vdisk and disk group after upgrading
An EVA Perf issue exists when upgrading an EVA3000 or EVA5000 from VCS v3.x to VCS v4.x. Following
theupgrade,EVAPerfwillnotbeabletodisplayVD(Vdisk)andVDG(VirtualDiskGroup)statisticswhen
EVAPer f i s run on a Windows host with LUN 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 present
ed to that Windows host. This situation does not occur on a new EVA3000 or EVA5000
running VCS v4.004, or a v3.x storage system that is uninitialized before it is upgraded.
The following technique can be used to avoid this s ituation:
• Ensure that EVAPerf is run on a host that never had LU N presentations from the storage system.
Typically, EVAPerf is run on a management server which will not h ave I/Os to the storage system.
In this configuration, the management server does not h ave any LUNs presented to it and this
issue will
not occur.
Ensure the latest connectivity requirements are met
Detailed system specifications for each supported operating system are included in a series of
Connectivity installation and reference guides and associated Connectivity release notes.Youcan
