6.0.2 HP IBRIX X9000 Storage Release Notes (AW549-96044, January 2013)

Upgrades
• If clients previously mapped a CIFS share using the hostname/FQDN, they will be prompted
continuously to enter their credentials when attempting to access the CIFS share after the upgrade.
(The share can be accessed successfully using the IP address.) To workaround this situation, disjoin
and then rejoin all file serving nodes to the Active Directory domain. This can be done using the
GUI or the ibrix_auth command.
General
• The ibrix_pv -a -o mpath command does not recognize a multipath device. The command
works properly when an argument is added to ignore the standard scsi devices. Execute the
command as follows, specifying the path to your device.
ibrix_pv -a -o accept:/dev/mapper/mpath10,~standard
• HP-OpenIPMI does not work with the HP-Health service. For example, Proliant health check tools
such as SMH and SIM and hpasmcli commands such as SHOW POWERSUPPLY do not report
errors. This situation occurs because X9000 Software requires standard RHEL IPMI. Remove the
HP-OpenIPMI RPM (execute rpm -e HP-OpenIPMI), and then start the standard RHEL IPMI
(execute /etc/init.d/ipmi start). The standard RHEL IMPI will now start automatically
when the server is booted.
• During server migration or failover, certain cluster events will be reported as alerts. These events
are expected and normal, and are reported temporarily as a server is failing over to another
server.
• Node failover does not occur when a node has a complete loss of power (for example, removing
power cords or pulling a blade from a chassis). Do not test high availability in this manner.
• The log files for user-initiated tasks (such as running ibrix_fsck and migrating or rebalancing
segments) are not rotated automatically. To control the space used by these log files, you will
need to maintain them manually. The log files are located in /usr/local/ibrix/log.
• NFS locks may return an error code (37) after an unlock operation even though the lock was
correctly released. If other results are normal, you can ignore this error code.
• Clients cannot view files containing Korean characters on an FTP share. To resolve this, set the
LANG variable to ko_KR.euckr.
Documentation additions
Following are additions to the X9000 documentation.
Updates to the Statistics tool documentation
The following changes apply to the chapter “Using the Statistics tool” in the administrator guides:
• The default value for the aging configuration parameter is now 24h (24 hours). Steps 4 and 5 in
the section “Enabling collection and synchronization” are now unnecessary.
• Historical data and reports are now written to /local/statstool/histstats by default. It
is no longer necessary to create a symbolic link to this folder, as described in the sections
”Maintaining the Statistics tool” and “Management console failover and the Statistics tool
configuration.” Also, it is no longer necessary to perform the backup steps listed under
“Management console failover and the Statistics tool configuration.”
Installing a minor kernel update on Linux clients
The X9000 client software is upgraded automatically when you install a compatible Linux minor kernel
update. If you are planning to install a minor kernel update, first run the following command to verify
that the update is compatible with the X9000 client software:
