Configuring SH043 Controller/Storage Cabinets
This chapter describes the configuration of SH043 controller/storage cabinets.
These storage subsystems use StorageWorks HS-family array controllers
mounted in SHxzz–zz shelves. Storage devices are housed in SHDZZ–ZZ shelves.
StorageWorks HS-family array controllers use the Small Computer System
Interface 2 (SCSI–2) interface as the communication path with the host computer.
The SCSI–2 interface is used as the storage device bus in all subsystems. SH043
controller/storage cabinets can be configured with up to four controllers in
redundant pairs and with up to nine storage shelves.
Refer to the
StorageWorks BA350–EA Modular Storage Shelf User’s Guide
for
further information on HS-family array controllers and their installation.
WARNING
While working in the cabinet interior, ac power must be removed from
cabinet components. Failure to do so may result in personnel injury as a
result of electric shock.
Prior to performing any of the procedures in this chapter, remove ac power from
the cabinet components. If the cabinet is installed and operating, spin down all
disk drives and halt all tape drives in the cabinet. Switch the circuit breaker on
the front panel of the cabinet’s cable distribution units (CDUs) to the
(OFF)
position.
5.1 Cabinet Configuration
WARNING
Failure to install cabinet components in the proper order could result in
cabinet instability, injury to personnel, and damage to equipment.
Note
To maintain FCC compliance and proper airflow, filler panels and air
separation panels must be installed as specified for your particular
cabinet configuration. See Section 5.2 for further information.
