Offline upgrades for X9000 software 5.6.x or 6.0.x to 6.1

Preparing for the upgrade

To prepare for the upgrade, complete the following steps:
1. Ensure that all nodes are up and running. To determine the status of your cluster nodes, check
the dashboard on the GUI or use the ibrix_health command.
2. Verify that ssh shared keys have been set up. To do this, run the following command on the
node hosting the active instance of the agile Fusion Manager:
ssh <server_name>
Repeat this command for each node in the cluster.
3. Note any custom tuning parameters, such as file system mount options. When the upgrade is
complete, you can reapply the parameters.
4. Ensure that no active tasks are running. Stop any active Remote Replication, data tiering, or
Rebalancer tasks running on the cluster. (Use ibrix_task -l to list active tasks.) When the
upgrade is complete, you can start the tasks again.
5. The 6.1 release requires that nodes hosting the agile management be registered on the cluster
network. Run the following command to verify that nodes hosting the agile Fusion Manager
have IP addresses on the cluster network:
ibrix_fm -f
If a node is configured on the user network, see
" (page 103)
6. Stop all client I/O to the cluster or file systems. On the Linux client, use lsof </mountpoint>
to show open files belonging to active processes.
7. On all nodes hosting the passive Fusion Manager, place the Fusion Manager into maintenance
mode:
<ibrixhome>/bin/ibrix_fm –m maintenance
8. On the active Fusion Manager node, disable automated failover on all file serving nodes:
<ibrixhome>/bin/ibrix_server -m -U
9. Run the following command to verify that automated failover is off. In the output, the HA column
should display off.
<ibrixhome>/bin/ibrix_server -l
10. Unmount file systems on Linux X9000 clients:
ibrix_lwumount -m MOUNTPOINT
1 1. Stop the CIFS, NFS and NDMP services on all nodes. Run the following commands on the
node hosting the active Fusion Manager:
ibrix_server -s -t cifs -c stop
nl
ibrix_server -s -t nfs -c stop
nl
ibrix_server -s -t ndmp -c stop
If you are using CIFS, verify that all likewise services are down on all file serving nodes:
ps –ef | grep likewise
Use kill -9 to stop any likewise services that are still running.
If you are using NFS, verify that all NFS processes are stopped:
ps –ef | grep nfs
for a workaround.
