Expanding data (user) volumes

This topic describes how to increase the size of a user volume when the corresponding data LUN size has increased.

Prerequisites

You must have Administrator privileges to perform this task.

Context

Attention: You must reboot the client machines (except AIX® 5.2 and later clients) that have access to the expanded volumes to see the expanded volume size.

Steps

  1. Resize one or more data LUNs on your storage system (for example, IBM® TotalStorage® SAN Volume Controller (SVC)).
  2. For each AIX 5.2 and later clients, perform these steps:
    1. Stop each application that is using SAN File System.
    2. Stop the AIX client using the rmstclient command.
    3. Start the AIX client using the setupstclient command.
  3. For all other clients, reboot each machine.
  4. Verify that all clients can see the new volume size using the reportclient –lun command from the administrative CLI.
  5. Expand the size of each volume (associated with the LUNs you expanded on your storage subsystem) on the metadata server using the expandvol command from the administrative CLI or using the SAN File System console perform the following steps:
    1. Click Manage Storage > Volumes from the My Work frame.
    2. Select a volume.
    3. Click Properties from the drop-down box in the table header.
    4. Click Go
    5. Click the Size tab.
    6. Determine the current LUN size by selecting a client that can see the LUN from the drop-down box and clicking Refresh.
    7. Check the LUN size versus the volume size in the table and click Expand Volume to increase the volume size if the LUN size has increased.
    8. Click OK to save the new settings.
