5.6.4 HP StoreAll Storage Release Notes (AW549-96075, June 2013)

The following example is for a RHEL 4.8 client with kernel version 2.6.9-89.ELsmp:
# /usr/local/ibrix/bin/verify_client_update 2.6.9-89.35.1.ELsmp
nl
Kernel update 2.6.9-89.35.1.ELsmp is compatible.
If the minor kernel update is compatible, install the update with the vendor RPM and reboot the system.
The StoreAll client software is then automatically updated with the new kernel, and StoreAll client
services start automatically. Use the ibrix_version -l -C command to verify the kernel version
on the client.
Support Ticket configuration
The following information corrects the information about SSH keys included in “Managing support
tickets” in the 9300, 9320, and X9720 administrator guides.
The Support Ticket feature requires that two-way shared SSH keys be configured on all file serving
nodes. If shared SSH keys are not configured on your cluster, use the following procedure to configure
them:
1. On all file serving nodes and the management console, run the following commands as root:
# mkdir -p $HOME/.ssh
# chmod 0700 $HOME/.ssh
# ssh-keygen -t dsa -f $HOME/.ssh/id_dsa -P ''
This command creates two files: $HOME/.ssh/id_dsa (private key) and $HOME/.ssh/
id_dsa.pub (public key).
2. On each file serving node and the management console, run the following command, once for
each file serving node (including the node where the command is issued) and once for the
management console:
# ssh-copy-id -i $HOME/.ssh/id_dsa.pub server
3. On all file serving nodes and the management console, test the results by using the ssh command
to connect to each file serving node and the management console:
# ssh {hostname for file serving node}
Joining X9720 systems
When joining multiple X9720 systems into a single cluster, it is important that the ibrix_vs command
be used in the following manner.
Run the ibrix_vs command individually for each of the X9720 racks, as if they were standalone
systems. For example, if three X9720 systems will be joined together, the ibrix_vs command must
be run three times. The parameters used must be only for the system being addressed, not the whole
cluster (that is, the host names and IP addresses used must be for that system only). The IBRIX OS
software will aggregate the data for the systems into the configuration.
Removing storage from the cluster
The following procedure replaces “Removing storage from the cluster” in the 9300, 9320, and X9720
administrator guides.
Before removing storage that is used for an IBRIX OS Software file system, you will need to evacuate
the segments (or logical volumes) storing file system data. This procedure moves the data to other
segments in the file system and is transparent to users or applications accessing the file system. When
evacuating a segment, you should be aware of the following restrictions:
• Segment evacuation uses the file system rebalance operation. While the rebalance task is running,
the system will prevents tasks from running on the same file system. Similarly, if another task is
running on the file system, the rebalance task cannot be scheduled until the first task is complete.
• You cannot evacuate or remove the root segment (segment #1).
