Configuring physical volumes
After you define supported physical disks on your disk subsystem, use the cfgmgr
command to make the supported physical disks known to the NAS Gateway 500
System Software. Use the NAS lspvol command to verify that the disks have been
properly configured. This command shows all the disks that are configured in your
NAS Gateway 500 system, the physical volume identifier (PVID), the NAS volume
to which it belongs, and a description for each disk is also displayed.
Configuring NAS volumes
The NAS Gateway 500 provides a wizard through WebSM for initial volume
management configuration. Click the WebSM icon on your managing console. The
WebSM main panel is displayed. From the navigation area, click
Volumes→Overview and Tasks→Create a NAS Volume. The Welcome to the NAS
Volumes Wizard panel is displayed. Read this panel and click the appropriate
button at the bottom of the panel. Continue using the wizard, providing information
where required, and clicking the button at the bottom of each panel. Each panel in
this wizard contains instructions for completing the required information. Help is
provided for some panels.
Creating a NAS volume
After storage has been set up and allocated on external disk storage, a NAS
volume can be created and configured for file serving. In a clustered system, a NAS
volume is associated with a group on a node. To create a NAS volume, use the
NAS command mkvol. This command uses the specified physical disks to create a
NAS volume. A NAS volume can span across multiple disks. This allows you to
create multiple volumes for multiple purposes, with varying storage sizes.
If the system has been configured for remote mirroring, the remote NAS volume
can also be created at the time the local volume is being created. If snapshots will
be remotely mirrored for this volume, select the proper option.
CLI command
To create a volume with the CLI, use the mkvol [ -r resource_group ] [ -n
num_snapshots [ -s snapshot_size ] ] [ -L ] volumename disk1 [ disk2 ... ] [ -g [ -c ]
-X node_name remote_disk1 [ remote_disk2... ] ] command.
Parameter
-n num_snapshots
-r resource_group
-s snapshot_size
-L
-g
-c
