HP StoreAll Storage - Manual (Page 16)

CLI procedures
The CLI commands are executed immediately on file serving nodes. For X9000 clients, the command
intention is stored in the management console. When X9000 Software services start on a client,
the client queries the management console for any commands. If the services are already running,
you can force the client to query the management console by executing either ibrix_client or
ibrix_lwmount -a
on the client, or by rebooting the client.
If you have configured hostgroups for your X9000 clients, you can apply a command to a specific
hostgroup. For information about creating hostgroups, see the administration guide for your system.
Creating mountpoints
Mountpoints must exist before a file system can be mounted. To create a mountpoint on file serving
nodes and X9000 clients, use the following command.
/bin/ibrix_mountpoint -c [-h HOSTLIST] -m MOUNTPOINT
To create a mountpoint on a hostgroup , use the following command:
/bin/ibrix_mountpoint -c -g GROUPLIST -m MOUNTPOINT
Deleting mountpoints
Before deleting mountpoints, verify that no file systems are mounted on them. To delete a mountpoint
from file serving nodes and X9000 clients, use the following command:
/bin/ibrix_mountpoint -d [-h HOSTLIST] -m MOUNTPOINT
To delete a mountpoint from specific hostgroups, use the following command:
/bin/ibrix_mountpoint -d -g GROUPLIST -m MOUNTPOINT
Viewing mountpoint information
To view mounted file systems and their mountpoints on all nodes, use the following command:
/bin/ibrix_mountpoint -l
Mounting a file system
File system mounts are managed with the ibrix_mount command. The command options and
the default file system access allowed for X9000 clients depend on whether the optional Export
Control feature has been enabled on the file system (see
“Using Export Control” (page 18) for
more information). This section assumes that Export Control is not enabled, which is the default.
NOTE: A file system must be mounted on the file serving node that owns the root segment (that
is, segment 1) before it can be mounted on any other host. X9000 Software automatically mounts
a file system on the root segment when you mount it on all file serving nodes in the cluster. The
mountpoints must already exist.
Mount a file system on file serving nodes and X9000 clients:
/bin/ibrix_mount -f FSNAME [-o {RW|RO}] [-O MOUNTOPTIONS] -h HOSTLIST
-m MOUNTPOINT
Mount a file system on a hostgroup:
/bin/ibrix_mount -f FSNAME [-o {RW|RO}] -g GROUP -m MOUNTPOINT
Unmounting a file system
Use the following commands to unmount a file system.
NOTE: Be sure to unmount the root segment last. Attempting to unmount it while other segments
are still mounted will result in failure. If the file system was exported using NFS, you must unexport
it before you can unmount it (see
“Exporting a file system” (page 38) ).
To unmount a file system from one or more file serving nodes, X9000 clients, or hostgroups:
