NOTICE:
RAID controller modules are hot-pluggable and can be removed and installed without shutting down the
enclosure. However, removing a controller module while data traffic is occurring that involves that controller could
cause data loss and is not recommended. Use the MD Storage Manager to take the RAID controller module off line
before removal.
NOTICE:
To prevent damage to your enclosure, you should wear a wrist grounding strap while performing the
following procedures. See your Product Information Guide for safety information.
1 Use MD Storage Manager to place the RAID controller module offline. See the MD Storage Manager
documentation for more information.
2 Remove the RAID controller module (see "Removing and Installing a RAID Controller Module" on
