Unlinking virtual disk drives from an AIX logical partition

By unlinking virtual disk drives (network-server storage spaces) from an AIX® logical partition that uses i5/OS® resources, you disconnect the virtual disk drives from the logical partition, making the virtual disk drives inaccessible to users. If you delete a AIX logical partition that uses i5/OS resources, you must unlink all virtual disk drives from the logical partition before you delete the logical partition.

1. Unlink disk drives from a logical partition using iSeries® Navigator. If you prefer to use a character-based interface, go to step 2.
   1. Vary off the NWSD for your logical partition. For more information, see Starting and stopping the network server description.
   2. Click Network > Windows Administration > Disk Drives.
   3. Right-click the name of the disk drive that you want to unlink.
   4. Click Remove Link.
   5. Select a server from the list of linked servers.
   6. If you are unlinking a disk drive that you plan to relink later, uncheck Compress link sequence. You must relink the disk drive as the same link sequence number before you vary on the server. By preventing compression of the link sequence values, you avoid having to unlink and relink all the disk drives to get them in the correct sequence.
   7. Click Remove.
   8. You have completed this procedure. Do not complete step 2.
2. Unlink disk drives from a logical partition using a character-based interface:
   1. Vary off the NWSD for your logical partition. For more information, see Starting and stopping the network server description.
   2. Type RMVNWSSTGL and press F4.
   3. In the Network-server storage space field, type the name of the storage space that you want to unlink and press Enter.
   4. In the Network server description field, type the name of the server from which you want to unlink the storage space and press Enter.
   5. If you are unlinking a linked disk drive that you plan to relink later, specify *NO in the Renumber field.
      Note: You must relink the disk drive as the same sequence number before you vary on the server. By preventing automatic renumbering, you avoid having to unlink and relink all the disk drives to get them in the correct sequence.
   6. Press Enter.
      Note: If you are uninstalling a logical partition, your next step is to delete the disk drive. For more information on deleting disk drives, see Deleting virtual disk drives for an AIX logical partition. Otherwise, vary on the NWSD for your logical partition. For more information about starting the NWSD, see Starting and stopping the network server description.
