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).
To delete existing LUs and replace them with new LUs:
- Issue the following CLI command to delete the managed disks (MDisks) that are associated
with the LUs from their storage pools:
rmmdisk -mdisk MDisk_name1:MDisk_name2 -force storage pool name
Where
MDisk_name1:MDisk_name2 are the names of the MDisks to delete. If you do
specify the -force parameter, an attempt is made to migrate the extents
that are in use onto other free extents within the storage pool. If there are not enough free
extents in the storage pool, the command will fail even if the -force
parameter is specified.
- Delete the existing LUs using the configuration software of the storage system.
- Issue the following command to delete the associated MDisks from the clustered system:
- Configure the new LUs using the configuration software of the storage system.
- Issue the following command to add the new LUs to the system:
