Issue
Description
Server ’s IP address may change if assigned with DHCP
When DHCP or DHCP reserv ations are used to assign IP addresses to servers, the
IP address can change when the server is rebooted. The D HCP server may be
slow to respond to the reboot, resulting in the server temporarily using a random
automatic IP address until the DHCP address is acquired. While the server has
the
temporary address it will not be able to rejoin the cluster, as HP Clustered File
System expects the server to have the DHCP address.
During this process, the cluster configuration might be destroyed on the rebooted
server; however, the configuration can be restored by importing it from another
node in
the cluster (or by exporting the configuration from a good node to the
rebooted server).
To avoid this problem, use static IP addresses for the servers that will be in the
cluster.
Third-party MPIO software must discover devices
When third-party MPIO software is used, it must discover and present storage
devices to t
he operating system before HP Clustered File System is configured
or
started.
If HP Cluste
red File System is star ted and the third-party MPIO software has not
previously
discovered the devices, HP Clustered File System will make a “best
effort” to
discover them. In some cases, HP Clustered File System will initiate a
single
reb
oot.
HP Clustered FileSystemwill not startifitcannotdiscover the devices. The
administrator must then determine why the MPIO devices have not been discovered
and
resolve the issue.
HP Clustered File System Installer does not find saved configuration
When HP Clustered File System is uninstalled, you can save the cluster
configuration. If you then reinstall HP Clustered File System in a different location,
the
Installer will not find the saved configuration. To avoid this problem, reinstall HP
Clustered File System in its original location. The Installer will then find the saved
configuration and apply it to the new installation of HP Clustered File System.
If you need to install HP Clustered File System in a new location, you will need
to
move the saved configuration files to the new location before the HP Clustered
File System installation.
Filesystem resize does not work correctly with mount points
The HP Management Console includes an option to extend the size of a filesystem.
After a filesystem is extended, HP Clustered File System at tempts to reassign the
drive letters or mount points associated with the filesystem. HP Clustered File
System reassigns drive letters correctly; however , it fails to reassign mount points.
You will need to recrea te the appropriate mount points manually after the extend
operation is complete.
To recreate the m ount points, first manually delete the old mount points (the empty
directories on the local NTFS volumes of each node). Next, recreate the empty
directories and then use the HP Management Console to reassign the mount
points manually.
