You can move volumes from one filer to another. You might want to move a volume to a different filer to perform one of the following tasks:
You can physically move disks, disk shelves, or loops to move a volume from one filer to another. You need the manual for your disk shelf to move a volume.
To move a volume, complete the following steps.
Step
|
Action
|
|---|
|
1 |
Enter the following command at the source filer to locate the disks that contain the volume:
vol status vol_name -r
Result
The locations of the data and parity disks in the volume appear under the volume name on the same line as the labels Data and Parity.
|
|
2 |
Follow the instructions in the disk shelf hardware guide to remove the disks, from the source filer.
|
|
3 |
Halt and turn off the destination filer.
|
|
4 |
Install the disks in a disk shelf connected to the destination filer.
|
|
5 |
Turn on and boot the destination filer.
Result
When the destination filer boots, it places the foreign volume off-line. If the foreign volume has the same name as an existing volume on the filer, the filer renames it volume_name(1), where volume_name is the original name of the volume.
Caution
If the foreign volume is incomplete, repeat Steps 1 and 2 to add the missing disks. Do not try to add missing disks while on-line--doing so causes them to become hot spare disks.
|
|
6 |
If the filer renamed the foreign volume because of a name conflict, enter the following command to rename the volume:
vol rename vol-name new-name
vol-name is the name of the volume you want to rename.
new-name is the new name of the volume.
Example
The following command renames the users(1) volume to newusers:
vol rename users(1) newusers
|
|
7 |
Enter the following command to bring the volume on-line in the new filer:
vol online vol-name
vol-name is the name of the volume.
Result:
The following events occur:
- The volume is on-line in its new location.
- Entries in the /etc/exports file and shares that refer to the volume become incorrect.
- The in-memory information about active exports gets updated automatically, and clients continue to access the exports without problems.
|
|
8 |
Enter the following command to confirm that the added volume came on-line:
vol status vol-name
vol-name is the name of the volume.
|
|
9 |
If you have...
|
Then...
|
An NFS-only filer
|
Go to Step 11.
|
A CIFS-only or multiprotocol filer
|
Create shares that refer to the new volume to enable clients to access it, then go to Step 10.
|
|
10 |
If you have...
|
Then...
|
A CIFS-only filer
|
You are done.
|
A multiprotocol filer
|
Go to Step 11.
|
|
11 |
Update the system /etc/exports file with the new volume.
|
|
12 |
Run exportfs.
|
|
13 |
Add the appropriate mount point information to the /etc/fstab or /etc/vfstab file on clients that mount volumes from the filer.
