Release Notes Product: AMASS for UNIX® Version 5.4 Operating Systems: IBM® AIX 5.1 and 5.2 (32-bit only) HP Tru64™ UNIX 5.1, 5.1A, and 5.1B HP-UX® 11.00 (32-bit and 64-bit) HP-UX® 11i (11.11) (32-bit and 64-bit) (PA-RISC only) SGI IRIX® 6.5.16m - 6.5.
New Features These features and enhancements are new in this release of AMASS for UNIX: • AMASS Read Only—AMASS read only allows users to set AMASS to a read only state. You can read from AMASS, but not write or delete. To change the state to read only we use the amasstat command. The options are as follows: Usage: amasstat [-aicfswuy] [-t sec] • -a Changes filesystem to active status. • -i Changes filesystem to inactive status (reads and writes from/to open files continue).
• • 4 = Sets scsi_verbose flag. • 8 = Sets select_debug flag (in libsched select_drive function). • 15 = ALL: 1+2+4+8 Enhanced Cache—There are enhancements to the AMASS feature Enhanced Cache Control. The core of AMASS is a cache in which data is held prior to migrating to/from media. The cache is broke up into cache blocks whose size is configurable. Without the Enhanced Cache Control feature turned on, AMASS reuses cache blocks which are the oldest on the cache.
• • -x Turns on SCSI debugging. • -j Directs the medialist command to jukebox ID rather than the default of 1. Network Attached Libraries—Enhancements to the network attached library interface include: • Reducing the number of 'query drive' commands thus softening the load on the XDI interface. A function to test the need to inquire about library drive status is added. If there are no drive candidates to service a pending IO request, the library query drive command is not called.
• -i Change volume status to inactive. • -f Sets a tape volume to NOT FULL. Adds the value vlk_maxxfr found in amass/scripts/amassconfig2 to the volume capacity. • -F Sets a tape volume to FULL. • -s Sets volume available (AVAIL) size (Mb) volstat -s • -u Displays this usage message. • -y Suppresses confirmation and informational messages. If -a or -i are not specified, then the active status of the specified volume is toggled.
• • 3800ux 128 slots • 7100ux 238 slots Plasmon G-Series with UDO The Plasmon G-Series libraries were previously supported with optical drives. Mixing drive types within the library is not currently supported. • G64 • G104 • G164 • G238 • G438 • G638 Additional firmware support includes: • ACSLS 7.0 • ACSLS 7.1 • Scalar i2000 library M1 firmware • Scalar i2000 library M2 firmware • Scalar DLC 2.

Upgrade Guidelines When upgrading to AMASS 5.4, please make note of the following upgrade guidelines. Operating System HP Tru64 Upgrade Guidelines To successfully install AMASS while using only part of a disk as the AMASS cache, you must first verify that the c partition of the disk has a file system type (fstype) of unused. Second, you must verify that the user amass has read/write permission to the raw c partition (for example, /dev/ rdisk/dsk2c).
SCSI-Attached Devices: Connect the storage devices to the SCSI bus on the server. Make sure the SCSI bus is properly terminated. Refer to your library’s user manual for instructions on setting the SCSI addresses. The AMASS installation script retrieves and displays device addresses to aid you in the AMASS configuration process. 7 Apply power to the storage devices and boot the UNIX server.
Fibre Channel Guidelines The following guidelines exist for AMASS running with fibre channel. HP-UX Fibre For AMASS users in a HP-UX fibre environment connected to a PathLight 5000 SNC, the environment variable: AMASS_PLSNK should be used. A known error condition exists where the first SCSI test-unit-ready sent to the device is never received but rather absorbed by the PathLight and a SCSI bus reset status returned.
# ls -l /hw/scsi total 0 drwxr-xr-x 2 root sys 0 Apr 24 12:38 1000006045170ad2 drwxr-xr-x 2 root sys 0 Apr 24 12:38 2000000087000b63 drwxr-xr-x 2 root sys 0 Apr 24 12:38 2000000087002b04 drwxr-xr-x 2 root sys 0 Apr 24 12:38 2000000087003124 3 Look at the contents of the node directory for that device.
Operating Guidelines When operating AMASS 5.4, please make note of the following operating guidelines. IRIX: Tape Support (TS) system The tape support (TS) system consists of a tape support driver, personality daemons, and a daemon to manage the personality daemons. Thie TS system is provided by SGI to manage tape devices. AMASS does not require the TS system to run and it has trouble if the TS system is controlling the AMASS drives. The mediad daemon initiates the ts daemon on the AMASS drives.
Known Issues Known issues in this release of AMASS for UNIX Version 5.4 are listed in the table below. In addition to the following known issues, be aware of the setup and operational guidelines. For more information, refer to “Installation Guidelines,” “Fibre Channel Guidelines,” and “Operating Guidelines” in this document.
