HP recommends the following:When attempting to create a cluster, the
cluster validation wizard fails, indicating
If one or more volumes were removed before running the validation
wizard, they may be flagged with warnings during the cluster validation
even though they do not exist. These warnings can be ignored.
a failure in the storage tests from the
Microsoft test report. The failure
described is the inability to write to one
of the disk partitions.
The network used for the cluster heartbeat uses APIPA (169.254.0.0/16)
addresses which will be flagged with warnings during the cluster
validation. These warnings can be ignored.
The cluster validation may indicate that one or more disks are corrupted.
When this happens the test terminates. You should run chkdsk.exe on
the disk. It is not important to use any options on the chkdsk command
line. For example, if the drive letter for the corrupted disk is Q: then you
would run chkdsk q:.
HP strongly recommends using Active Directory or other RFC2307 compliant
LDAP stores for NFS user name mapping. Using Active Directory Lightweight
The NFS user mapping should not use
ADLDS.
Data Services (ADLDS) is not recommended. Configuring ADLDS in a clustered
environment is beyond the scope of this document.
The Onboard Administrator GUI Launch button only applies to systems with
the C3000/C7000 chassis. You are not able to use this button with the
X5000 G2 Network Storage System.
The Onboard Administrator GUI cannot
be launched from the Integrated
Lights-Out 3 page. The Launch button is
in the Active Onboard Administration
section under the BL c-Class node in the
Integrated Lights-Out 3 navigation tree.
Update the SAS I/O module firmware again. If the second update is
unsuccessful, review the log file for more information.
On rare occasions, an update to the SAS
I/O module firmware may result in the
following message: Flash failed
for xxxx half of SAS I/O
Module. Check log file yyyy
for more information (where xxxx
is internal or external and yyyy is the
path and name of the log file).
Identify and reseat the SAS I/O module that is causing the issue. An I/O
module may need to be replaced if there is less information available for
one I/O module than the other.
If the System Management Homepage
lists a fan module as unknown or
dormant, it might not be a fan issue. It
may mean that a SAS I/O module needs
to be reseated.
An alert is generated for cache and supercapacitor (cache backup) issues,
but you can also run the following command from a command prompt or
PowerShell to determine the issue:
