Upgrading the system
1. Export volumes from the existing node. If volumes had been previously defined
2. Run WebSM Initial Configuration Wizard on the joining node:
3. Import the volumes that were exported from the existing node to the newly
on the existing node which will now be part of a cluster, and those volumes are
to be restored after the upgrade, then the volumes must be exported now. Once
cluster configuration is complete they can then be imported to the dual-node
system. To export volumes from the existing node system:
a. Log in as root user to the existing single-node NAS Gateway 500.
b. Run the /opt/nas/bin/lspvol command and record the information on each
physical volume identifer (PVID) and its corresponding volume.
c. Record and remove all NFS exports and CIFS shares (this can be done
through SMIT or WebSM).
d. Run the /opt/nas/bin/expvol <volume to be exported> command on all
volumes.
a. Note: Skip this step if you already have the remote client installed on a
graphics-capable machine. There is no need to download and install this
client again.
Point your browser to the IP address of the joining node. Select
Language→Continue→Download (WebSM setup.exe) to install WebSM
client, if necessary. Execute WebSM setup.exe to create a WebSM client
icon on your desktop.
b. Click on WebSM client icon, fill in Host Name (is the IP address of the
node), and log on as root user to the joining node. The Welcome screen
appears on the upper left corner.
c. Click the Initial Configuration Wizard, and select your purchased features
from the Feature management screen:
v Clustering feature (a single-site, dual-node cluster is configured if this
feature is selected without Remote Mirroring)
v Remote Mirroring (a dual-site Geographic Cluster is configured if this
feature is selected)
v CIFS feature (a CIFS server is configured if this feature is selected)
d. Fill in the rest of the screens as appropriate. Any NAS Administrators and
file access users must be redefined (either during or after WebSM initial
configuration), so that they exist on both nodes of the cluster.
e. Create additional new volumes as needed. If you do not need to create new
volumes, continue past the Volume Management screens and click Finish to
exit the wizard.
configured dual-node cluster:
a. From the Web-based System Manager window, select NAS
Management→NAS System→Volumes→Overview and Tasks→Import a NAS
Volume.
b. Select the new group from the pull-down list. This new group may be the
original node where this volume was exported or the new joining node.
Complete the New Volume Name, and select Disk Containing Volume from
the pull-down hdisk list whose PVID corresponds to one of the PVIDs on
which the volume resides (using the information recorded in step 1b). Click
OK. Repeat for all volumes to be imported.
c. After importing the NAS volumes, recreate the NFS exports and CIFS
shares, using the information recorded in step 1c). Click Start local CIFS
server operations to start the CIFS server if necessary. From Web-based
