HP StorageWorks 9100 Extreme Data Storage System administration guide V1.0.2 (AN540-96018, February 2010)

• Storage—Issues connected with storage blocks (arrays) or the SAS fabric connecting servers to
storage blocks
• Firmware—Checks whether all components are at the correct firmware levels and also reports in-
consistencies between the firmware levels on different servers or arrays.
• Interconnect—Issues related to the networks
Syscheck report
HP recommends that you read the whole report, but if you prefer to focus on a specific category, use
the syscheck command as shown in the example:
# exdsmgr syscheck enable=firmware
To disable a specific category, for example, iLO, enter the following command:
# exdsmgr syscheck disable=ilo
Most reports are self-explanatory. For example, this report indicates that the firmware version in the
HP ExDS9100cc controller is outdated:
Array 1 Controller 0 firmware (0120.2008061301) is not >= 0122.2008071101
and is not supported
For some conditions, the syscheck report also contains information about the components that might
be affected (impacted) by the error condition. For example, the following report says that since servers
7 through 16 do not have access to some LUNs, the /var/mxso utility filesystem could have problems
on those servers:
glory[7-16] do not have access to LUNs [1-4]
Impacts PSDs: psd[1-2], PSVs: psv1, Filesystems: /var/mxso
The “impacts” statement lists all related objects. In this example, there is a chain of consequences.
The LUNs have a problem; therefore, some psd devices have a problem. Because a matrix volume
uses those psds, the volume psv1 has a problem. Finally, the /var/mxso filesystem is based on psv1.
By default, the exdsmgr syscheck command prints to stdout. You can direct the report to a file
as shown in the following example:
# exdsmgr syscheck report=/tmp/syscheck-report.txt
