Installation And Upgrades - HP StoreVirtual 4000 Release Note

Undefined and Unknown values are showing for Usage Remaining and Wear Status of drives
under SmartSSD Wear Gauge in System Management Homepage for P4900 G2 SSDs
The System Management Homepage displays incorrect values for the SSD status. The correct
status is viewable on the ADU. The CMC also reports the correct status in the following locations:
◦
The Hardware Information report in the storage system Diagnostics category
◦
The Disk Setup tab in the storage system Storage category
An event email is also generated with the SSD status.
The CMC reports a drive status as Active and Normal, but the Drive Status is degraded in iLO
The iLO reports the HDD status as Degraded, but the CMC shows the drive as Active on the
Storage category Disk Setup tab. The Hardware Information report shows the drive status as
Normal and in the Diagnostics tests, the Disk Smart Health test passes. This issue is due to failed
communication with the drive carrier. The ADU and iLO logs show warning message
"Authentication on this drive carrier failed due to a communication error. This may not be an
authentic HP carrier. I/O operations to the device will not be affected, but the Smart Array
controller will not control the LEDs to this device." However the problem was not communicated
to the CMC.
The raw capacity and usable disk space are reported in different units of measurement for an HP
StoreVirtual storage system
Due to the different units of measurement between Terabytes (TB) and Tebibytes (TiB), the raw
capacity reported in an HP StoreVirtual storage system may appear to be lower than expected. One
TB of data is 10^12 bytes where a TiB is 2^40 bytes, a difference of approximately 100 GB. The
CMC reports values in TiB and HDD manufacturers typically report their size in TB. For example,
a 3 TB HDD would be reported as having a size of 2793.97 GB by the CMC. For an HP
StoreVirtual 4330 storage system with 8 1 TB HDDs, a raw capacity of 7 TB would be expected
when using RAID 5 (where one drive is used for data parity), but the CMC would report a raw
capacity of 6519.26 GB. This is the expected behavior, and it is simply two different methods
of representing the same number of bytes.

Installation and upgrades

A CMC on a Windows 2008 Server is unable to automatically discover storage systems if the
firewall is on
Disable the Windows Firewall on the computer on which the CMC is installed.
To ensure desired system settings are retained after upgrading from version 8.5, use Copy
Configuration before upgrading
Storage system settings are not retained after upgrading from version 8.5 to version 10.0. In the
case of storage systems in a management group, one storage system in the group serves as the
source for the settings that are applied to all the storage systems being upgraded. Therefore, use
the Copy Configuration function in a version 8.5 or earlier CMC to apply the desired settings to
all the systems that will be upgraded.
The storage system settings that may be retained after upgrading to version 10.0 include settings
for the following features:
◦
Alerts, including Alert emails
◦
SNMP general settings and traps
◦
Remote log files
