You must create at least one volume on a shared pool before you migrate it. As a best practice, we recommend that you create only one volume per shared pool.
IMPORTANT:Before adding volumes on a shared pool, make sure that the pool is mounted on the server where the pool was created. This is necessary because the Pool object information is relative to the Server object of the server where the pool was created.
When you create a volume, commands are added to the pool resource load and unload scripts to automatically mount and dismount the volume when the scripts run. You can modify the load script to comment out the mount command so that you can manually mount the volume on a node in the cluster where the pool resource has been activated.
When you create an encrypted NSS volume in a shared pool, you must mount the volume manually by using NSSMU and enter the password. NSS uses the password to create a key. Instead of storing it in the server memory as it does for non-shared volumes, NSS asks Novell Cluster Services to store the key and to pass it to the other nodes. After all servers hold the key, the volume is available for access as long as any one of the servers is still participating actively in the cluster. If all of the servers in the cluster fail, you must repeat this manual mounting procedure when you recover the cluster and restart services.
You can create NSS volumes by using the Storage plug-in to Novell iManager or the server-based NSSMU tool. For planning and management information, see the OES 2 SP2: NSS File System Administration Guide.
Repeat the following procedure for each cluster volume that you want to create on the shared pool.
Make sure the pool resource is mounted on the same server in the cluster where the pool was created.
Start your Internet browser and enter the URL for iManager.
The URL is http://server_ip_address/nps/imanager.html. Replace server_ip_address with the IP address or DNS name of a server in the cluster that has iManager installed or with the IP address for Apache-based services.
Specify your username and password, specify the tree information, then click .
In the left column, select , then select the .
Specify a cluster server name or browse and select one, then click .
Select the server where the shared pool was originally created and is currently mounted.
Specify the new volume name, then click .
Select the check box next to the cluster pool where you want to create the volume and either specify the size of the volume () or select , then click .
The volume quota is the maximum possible size of the volume. If you have more than one volume per pool, you can specify a quota for each volume rather than allowing multiple volumes to grow to the pool size.
Review and change volume attributes by selecting or deselecting the check boxes next to the attributes.
The Backup and Salvage Files attributes are selected by default.
For information about volume attributes, see Volume Attributes
in the OES 2 SP2: NSS File System Administration Guide.
Choose whether you want the volume activated and mounted when it is created, then click .
Repeat the following procedure for each cluster volume that you want to create on the shared NSS pool.
Make sure the pool resource is mounted on the same server in the cluster where the pool was created.
Start NSSMU by entering nssmu at the terminal console of the cluster server where the pool was originally created and is currently mounted.
From the NSSMU main menu, select .
On the Volumes page, press Insert, type a name for the new volume you want to create, then press Enter.
Each shared volume in the cluster must have a unique name.
Specify Y(es) to encrypt volume or N(o) to create a regular volume.
From the list of available pools, select the pool where you want the volume to reside, then press Enter.
The new volume appears in the list of volumes.
(Optional) From the list of volumes, select the newly created volume, then Press F5, , to review and change volume attributes, then select and press Enter to save any changes.
The default settings for new volumes are described in the following table:
For information about volume attributes, see Volume Attributes
in the OES 2 SP2: NSS File System Administration Guide.
Exit NSSMU.
