Replacing SAS connectivity modules with SAS RAID controller modules
If you are currently using SAS connectivity modules and you want to replace them with SAS RAID controller modules, make sure that you back up your existing data before you install the SAS RAID controller modules.
Note
If you are going to implement SAS RAID controller modules, make sure that you have SAS hard disk drives installed in any attached storage modules. The use of SATA hard disk drives is not supported with SAS RAID controller modules.
Perform these steps to replace SAS connectivity modules with SAS RAID controller modules:
- Back up all data that is currently stored on the hard disk drives. For example, you can use SAMBA or an NFS mount through the operating system to back up data.
- Shut down the operating system on all blade servers that access the hard disk drives.
- Disconnect the BladeCenter S chassis from all power sources.
- Remove the SAS connectivity modules from I/O module bays 3 and 4.
- Install the battery backup units in the media tray.
- Install the SAS RAID controller modules.NoteRemember that you must replace any SATA
hard disk drives with SAS hard disk drives. - Connect the BladeCenter S chassis to power.
- Configure the SAS RAID controller modules and integrated shared storage by creating storage pools, creating volumes, and mapping volumes to blade servers. You can use Storage Configuration Manager to configure your integrated shared storage.
- Copy all data from the backup location to the new volumes, using appropriate backup and restore tools.
