6.0 HP X9320 Network Storage System Administrator Guide (AW542-96009, December 2011)

6. If you are using CIFS, set the following parameters to synchronize the CIFS software and the
management console database:
• smb signing enabled
• smb signing required
• ignore_writethru
Use ibrix_cifsconfig to set the parameters, specifying the value appropriate for your
cluster (1=enabled, 0=disabled). The following examples set the parameters to the default
values for the 6.0 release:
ibrix_cifsconfig -t -S "smb_signing_enabled=0,
smb_signing_required=0"
ibrix_cifsconfig -t -S "ignore_writethru=1"
The SMB signing feature specifies whether clients must support SMB signing to access CIFS
shares. See the HP X9000 File Serving Software File System User Guide for more information
about this feature. Whenignore_writethru is enabled, X9000 software ignores writethru
buffering to improve CIFS write performance on some user applications that request it.
7. Mount file systems on Linux X9000 clients.
Manual upgrade procedure
The manual upgrade process requires external storage that will be used to save the cluster
configuration. Each server must be able to access this media directly, not through a network, as
the network configuration is part of the saved configuration. HP recommends that you use a USB
stick or DVD.
NOTE: Be sure to read all instructions before starting the upgrade procedure.
To determine which node is hosting the agile management console configuration, run the ibrix_fm
-i command.
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 management console:
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. 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 6.0 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 management
console have IP addresses on the cluster network:
ibrix_fm -f
If a node is configured on the user network, see “Node is not registered with the cluster network
” (page 92) for a workaround.
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.
