4-Port Shared Storage Module Option
The MSA500 system ships standard with a 2-Port Shared Storage Module. To
upgrade the unit and enable data transfer through four SCSI ports, install the optional
4-Port Shared Storage Module.
IMPORTANT: Before installing the 4-Port Shared Storage Module option, always upgrade to
the most recent firmware for the server host bus adapters (HBAs) and the MSA500
Controllers. The firmware upgrades ensure that HBAs can negotiate I/O paths with the storage
system controllers. For the most recent firmware, refer to the software CD that ships with the
Smart Array Multipath Software CD or refer to www.hp.com.
To install the module:
1. Power down the system. Refer to “System Power Down” in this chapter.
2. Disconnect the SCSI cabling connected to the 2-Port Shared Storage Module.
