Adding Additional Storage Enclosures
This section describes how to add single bus enclosures or dual bus enclosures to
the MSA1000 storage subsystem. It does not cover adding disk drives to the
MSA1000 or to disk enclosures already attached.
Older storage systems with high voltage SCSI connections cannot be attached to
the MSA1000.
Methods of expanding:
■ Migrating existing storage enclosures from an HP Smart Array to the
MSA1000
■ Adding a new storage enclosure
Note: Refer to the MSA1000 website: www.hp.com/go/msa1000 , for the most
up-to-date information on supported enclosures.

Migrating Existing Storage Enclosures
Even though extensive design and testing has been performed, when migrating
enclosures it is recommended to perform a back up of your data before you
migrate the enclosure to the MSA1000. Perform disk administration steps to
defragment your file systems or volumes prior to performing the backup, which
allows more efficient use of your backup media and reduces the time for backup.
The following steps provide an overview of migrating a new enclosure to an
existing MSA1000:
1. After backing up the storage systems, schedule a convenient time to shut
down the servers/applications so the storage subsystem can be turned off.
2. Shut down both the system(s) from which you are removing the disk
enclosure(s) and the target system to which you are planning to
migrate/consolidate your storage.
3. Disconnect the SCSI cables from your host bus adapter and storage enclosure.
If necessary, move the disk enclosure(s) to the new server rack using the
existing rack mount hardware.
4. Attach SCSI cables to the MSA1000 expansion SCSI connectors.
See Figure 31 for an illustration of the SCSI connectors.
