Recovering from disk failure while the system remains available

Edit online

You can recover from disk failure using the hot removability feature.

The procedure to recover from disk failure using the hot removability feature is, for the most part, the same as described in Disk drive recovery without reformatting, with the following exceptions:

  1. To unmount file systems on a disk, use the procedure Mount a JFS or JFS2.
  2. To remove the disk from its volume group and from the operating system, use the procedure Removing a disk without data.
  3. To replace the failed disk with a new one, you do not need to shut down the system. Use the following sequence of procedures:
    1. Logical volume storage
    2. Configuring a disk
    3. Continue with step 13 of Recovering by using a reformatted or replacement disk drive.
