Installation Procedures - All Deployments - To provide redundant storage, configure your Logical Units (LUNs) using fault-tolerant Redundant Array of Independent Disks (RAID) levels and striping methods. Stripe the LUNs vertically across separate storage enclosures on different SCSI buses, including drives from each bus. - To provide redundant data paths, you must include two separate and isolated Fibre Channel fabrics and the associated hardware and software components in the configuration. You must include two MSA controllers, two Fibre Channel interconnect devices (switches/fabrics), and a minimum of two HBAs per server. In addition, multipathing software must be installed on each server with access to the MSA. ■ When handling hard drives, follow industry-standard practices. Internal storage media can be damaged when drives are shaken, dropped, or roughly placed on a work surface. When removing a drive, press the release button, and then pull the drive only slightly out of the enclosure. Then, to allow time for the internal disk to stop rotating, wait approximately 10 seconds before completely removing the drive from the enclosure. ■ If your environment includes multiple servers, HP recommends designating one of the servers as a management server, to centralize management tasks. It is on this server that you install management software such as the ACU, and it is from this server that you perform SAN management tasks. ■ When installing or updating HBA drivers, always use the drivers and installation scripts provided on the MSA Support Software CD and the MSA1500 website.

HP StorageWorks 1500 Modular Smart Array Installation Guide
—
To provide redundant storage, configure your Logical Units (LUNs) using
fault-tolerant Redundant Array of Independent Disks (RAID) levels and
striping methods. Stripe the LUNs vertically across separate storage
enclosures on different SCSI buses, including drives from each bus.
—
To provide redundant data paths, you must include two separate and
isolated Fibre Channel fabrics and the associated hardware and software
components in the configuration. You must include two MSA controllers,
two Fibre Channel interconnect devices (switches/fabrics), and a
minimum of two HBAs per server. In addition, multipathing software
must be installed on each server with access to the MSA.
■
When handling hard drives, follow industry-standard practices. Internal
storage media can be damaged when drives are shaken, dropped, or roughly
placed on a work surface. When removing a drive, press the release button,
and then pull the drive only slightly out of the enclosure. Then, to allow time
for the internal disk to stop rotating, wait approximately 10 seconds before
completely removing the drive from the enclosure.
■
If your environment includes multiple servers, HP recommends designating
one of the servers as a management server, to centralize management tasks. It
is on this server that you install management software such as the ACU, and it
is from this server that you perform SAN management tasks.
■
When installing or updating HBA drivers, always use the drivers and
installation scripts provided on the MSA Support Software CD and the
MSA1500 website. The MSA will not operate as intended if you update your
HBA driver manually or use drivers obtained from the HBA manufacturer.
■
When assigning system names and aliases, use only the following characters:
—
Uppercase alpha characters (A-Z)
—
Lowercase alpha characters (a-z)
—
Numeric characters (0-9)
—
Special characters (! # + ( ) ’ ; , . and space)
■
If you are connecting the MSA to existing servers, you may need to re-install
some of your management software after installing the MSA.
