6.3 HP StoreAll Storage Release Notes (TA768-96086, April 2013)

Email notifications do not include information about failed attempts to collect the cluster
configuration.
In some situations, ibrix_collect successfully collects information after a system crash but
fails to report a completed collection. The information is available in the /local/ibrixcollect/
archive directory on one of the file serving nodes.
Cluster component states
Changes in file serving node status do not appear on the management console until 6 minutes
after an event. During this time, the node status may appear to be UP when it is actually DOWN
or UNKNOWN. Be sure to allow enough time for the management console to be updated before
verifying node status.
Generally, when a vendorstorage component is marked Stale, the component has failed
and is not responding to monitoring. However, if all components are marked Stale, this implies
a failure of the monitoring subsystem. Temporary failures of this system can cause all monitored
components to toggle from Up, to Stale, and back to Up. Common causes of failures in the
monitoring system include:
Reboot of a file serving node
Network connectivity issues between the management console and a file serving node
Resource exhaustion on a file serving node (CPU, RAM, I/O or network bandwidth)
While network connectivity and resource exhaustion issues should be investigated, they can occur
normally due to heavy workloads. In these cases, you can reduce the frequency at which
vendorstorage components are monitored by using the following command:
ibrix_fm_tune -S -o vendorStorageHardwareStaleInterval=1800
The default value of this command is 900; the value is in seconds. A higher value reduces the
probability of all components toggling from Up to Stale and back to Up because of the conditions
listed above, but will increase the time before an actual component failure is reported.
SNMP
When the StoreAll SNMP agent is configured, do not restart snmpd. If the snmpd restart
command is run on the active node, you will need to take one of these steps:
If Phone Home was configured, reconfigure it.
If Phone Home was not configured, reconfigure the StoreAll SNMP agent.
HP Insight Remote Support
After HP Insight Remote Support is configured, do not restart snmpd. See “SNMP” (page 18) for
more information.
In certain cases, large number of error messages such as the following appear in /var/log/
hp-snmp-agents/cma.log:
Feb 08 13:05:54 x946s1 cmahostd[25579]: cmahostd: Can't update OS
filesys object: /ifs1 (PEER3023)
This error message occurs because the file system exceeds <n> TB. (This situation will be corrected
in a future release.) To disable logging, edit the script /opt/hp/hp-snmp-agents/server/
etc/cmahostd and remove the option -l <logname>. Then restart the agents using service
hp-snmp-agents restart.
If you want to keep logging enabled, be aware that the log messages occur frequently, and you
will need to monitor and clean up the log file regularly to avoid filling the file system.
