Record all host tunings, FS tunings and FS mounting options by using the following
commands:
10
1. To display file system tunings, enter: ibrix_fs_tune -l
>/local/ibrix_fs_tune-l.txt
2. To display default StoreAll tunings and settings, enter: ibrix_host_tune -L
>/local/ibrix_host_tune-L.txt
3. To display all non-default configuration tunings and settings, enter: ibrix_host_tune
-q >/local/ibrix_host_tune-q.txt
Ensure that the "ibrix" local user account exists and it has the same UID number on all the
servers in the cluster. If they do not have the same UID number, create the account and
change the UIDs as needed to make them the same on all the servers. Similarly, ensure
that the "ibrix-user" local user group exists and has the same GID number on all servers.
11
Enter the following commands on each node:
grep ibrix /etc/passwd
grep ibrix-user /etc/group
Ensure that all nodes are up and running. To determine the status of your cluster nodes,
check the health of each server by either using the dashboard on the Management Console
or entering the ibrix_health -i -h <hostname> command for each node in the
cluster. At the top of the output look for “PASSED.”

If you are running StoreAll 6.2.x or earlier and you have one or more Express Query
enabled file system, each one needs to be manually upgraded as described in “Upgrading
pre-6.3 Express Query enabled file systems” (page 18).
13
IMPORTANT: Run the steps in “Required steps before the StoreAll Upgrade for pre-6.3
Express Query enabled file systems” (page 18) before the upgrade. This section provides
steps for saving your custom metadata and audit log. After you upgrade the StoreAll
software, run the steps in “Required steps after the StoreAll Upgrade for pre-6.3 Express
Query enabled file systems” (page 19). These post-upgrade steps are required for you to
preserve your custom metadata and audit log data.
Online upgrades for StoreAll software
Online upgrades are supported only from the StoreAll 6.x release. Upgrades from earlier StoreAll
releases must use the appropriate offline upgrade procedure.
When performing an online upgrade, note the following:
• File systems remain mounted and client I/O continues during the upgrade.
• The upgrade process takes approximately 45 minutes, regardless of the number of nodes.
• The total I/O interruption per node IP is four minutes, allowing for a failover time of two minutes
and a failback time of two additional minutes.
• Client I/O having a timeout of more than two minutes is supported.
Preparing for the upgrade
To prepare for the upgrade, complete the following steps, ensure that high availability is enabled
on each node in the cluster by running the following command:
ibrix_haconfig -l
If the command displays an Overall HA Configuration Checker Results - PASSED
status, high availability is enabled on each node in the cluster. If the command returns Overall
HA Configuration Checker Results - FAILED, complete the following list items based
on the result returned for each component:
