HP StorageWorks 1510i Modular Smart Array installation and user guide (383070-002, July 2008)

Adding or migra
ting hard drives, enclosures, and arrays
This section de
scribes the following common migration scenarios:
• Adding new hard drive storage enclosures
• Migrating existing storage enclosures
• Migrating the
hard drives that make up an array
NOTE:
For the most up-to-date information on supported storage enclosures, see the MSA website.
Adding new hard drive storage enclosures
NOTE:
New storage enclosures with unconfiguredharddrivesarehotpluggable.
Perform the f
ollowing steps to attach a new hard drive storage enclosure to an existing MSA array:
1. From your man
agement utility such as the SMU, ACU, or MSA-CLI, generate a record of your
current con
figuration.
2. Install the new hard drive storage enclosures in the rack. For instructions, see the documentation
shipped with the rack or the enclosure.
3. Install th
e hard drives in the enclosure bays.
4. Connect the SCSI cables between the storage enclosures and the MSA array.
5. Connect the power cords to the storage enclosures.
6. Power on t
he new storage enclosures.
7. Wait for t
he storage enclosures to complete their startup routines.
8. Power cycle the MSA array, so that it will discover the new enclosures.
9. From each server, access the MSA management utility, such as the SMU, ACU, or MSA-CLI to
configure the new storage. For instructions, see the user documents for the utility.
10. In iSCSI environments, be sure to enter the iSCSI configuration settings and map the newly configured
LUNs to
iSCSI targets.
Migrating existing storage enclosures
Even though extensive design and testing has been performed, HP recommends backing up data
before migrating the enclosure to the MSA. Perform the administrative steps to defragment file systems
or volumes prior to performing the backup. This allows more efficient use of your backup media and
reduces the time for backup.
Perform the following steps to migrate an existing storage enclosure to an existing MSA:
IMPORTANT:
SCSI and SATA storage enclosures can be migrated. MSA1510i configurations have one limitation:
MSA20 SATA storage enclosures that are direct-connected to a server cannot be migrated to the
MSA1510i.
