Changing the configuration of an existing storage system using the CLI

You can use the command-line interface (CLI) to change the configuration of an existing storage system. You must change the configuration for a storage system when you want to delete and replace logical units (LUs).

Perform the following steps to delete existing LUs and replace them with new LUs:

  1. Issue the following CLI command to delete the managed disks (MDisks) that are associated with the LUs from their MDisk groups:
    svctask rmmdisk -mdisk MDisk name1:MDisk name2 -force MDisk group name

    Where MDisk name1:MDisk name2 are the names of the MDisks to delete.

  2. Delete the existing LUs using the configuration software of the storage system.
  3. Issue the following command to delete the associated MDisks from the cluster:
    svctask detectmdisk
  4. Configure the new LUs using the configuration software of the storage system.
  5. Issue the following command to add the new LUs to the cluster:
    svctask detectmdisk
