7. Reinsert all of the drives that made up a single array into the empty bays of
the storage enclosure. Do not insert the drives into empty bays that are part of
another array definition whose drives are still inserted in the storage
enclosures. Data on the drives that you insert is replaced with the
reconstructed data from the previously installed RAID array.
8. The system does not bring the array online automatically. You must use the
Import function to import the array configuration and place the array online.
9. Repeat steps 7 and 8 for each of the arrays that were removed from the
storage enclosure.
10. Use the DS Storage Manager Client program to save a storage subsystem
profile and collect the all support data bundle. This information is necessary
to restore a storage subsystem configuration in the event of a catastrophic
failure. Migration from one storage subsystem configuration to another
requires that you save both storage subsystem configuration profiles and
collect all support data bundles. For more information, see the DS Storage
Manager Client program Subsystem Management window online help, or go
to http://www.ibm.com/systems/support/storage/disk/ to access the latest
applicable IBM System Storage DS Storage Manager Version 11.2 Installation and
Host Support Guide.
Important: To avoid loss of data if a RAID array failure occurs, do not store
storage subsystem profiles and collect all support data bundles in the same
location as the logical drives.
Note: Do not reinsert drives from multiple arrays in random order into the
storage enclosures.
