Chapter 6 HPSS Configuration
390 September 2002 HPSS Installation Guide
Release 4.5, Revision 2
The STK RAIT PVR cannot be supported at this time since STK has not yet made RAIT
generally available.
The SSI requires that the system environment variables CSI_HOSTNAME and
ACSAPI_PACKET_VERSION be correctly set. Note that due to limitations in the STK Developer's
Toolkit, if the SSI is not running when the HPSS PVR is started, or if the SSI crashes while the HPSS
PVR is running, the HPSS PVR will lock up and will have to be manually terminated by issuing a
kill -9 command.
6.8.13.4.2 Configuration Requirements
When configuring HPSS to manage an STK Silo, the Drive Address configuration entries
correspond to the ACS, Unit, Panel, Drive number used by ACSLS to identify drives. For example,
the first drive in a typical Silo configuration has the Drive Address (0,0,10,0).
HPSS can share an STK robot with other tape management systems. If a robot is shared, care must
be taken to make sure that a drive is not used by any other tape management system while that
drive is configured as unlocked in HPSS. This is important because HPSS can be configured to
periodically poll all of its unlocked drives even if they are not currently mounted or in use by HPSS.
If a drive is being used by another tape management system, it must be configured as locked in
HPSS.
HPSS periodically polls all drives in its pool, so these drives cannot be used by other tape
management software when HPSS is running even if HPSS is not currently mounting tapes to those
drives.
HPSS will use any Cartridge Access Port (CAP) in the STK Silo that has a priority greater than zero.
When a CAP is neededby HPSS, HPSS will pick the highest priorityCAP that is currently available.
At least one CAP must be assigned a non-zero priority. See the STK Automated Cartridge System
Library Software (ACSLS) System Administrator’s Guide for procedures to set CAP priority.
6.8.13.4.3 Cartridge Import and Export
When importing new cartridges into HPSS, the cartridges must be entered into the STK Silo before
any HPSS import operations are performed. See the STK Automated Cartridge System Library
Software (ACSLS) System Administrator’s Guide for procedures to enter cartridges. When exporting
HPSS cartridges, the cartridges will be placed in the CAP for removal.
Cleaning cartridges are managed by the ACSLSsoftware andshould not beimported into the HPSS
system.
STK supports cartridges without bar code external labels. These cartridges can be entered into the
Silo using the venter command at the ACSLS console. These cartridges are fully supported by
HPSS, but the Silo will eject the cartridges if they are scanned during an audit.
6.8.13.4.4 Starting the STK Client Processes
In order for the HPSS PVR to communicate with the STK robot, it is required that STK client side
processes be running on the node where the HPSS PVR is executing. These client side processes are
