1 Release Notes


This Customer-Specific Patch Kit Distribution contains: 

   - fixes which are intended to resolve the problem(s) reported in: 
        o 96516 SIERRA-291 
             * for Tru64 UNIX V5.1B T64V51BB24AS0003-20030929.tar (BL24)

 WARNING! NOT FOR GENERAL USE.
          These patches are tailored for an individual system's hardware and
          software configuration. Use of this patch kit, or patches contained
          in this kit, on any other system may cause that system to be in an
          inconsistent and non-operational state.

          This patch kit, or its content, may not be posted on any network or
          bulletin boards.


 The Release Notes contain a summary of each patch in this kit.

 Patches in this kit are installed by running dupatch from the directory 
 in which the kit was untarred. For example, as root on the target system:

	> mkdir -p /tmp/CSPkit1
	> cd /tmp/CSPkit1
	> <copy the kit to /tmp/CSPkit1>
	> tar -xpvf DUV40D13-C0044900-1285-20000328.tar
	> cd patch_kit
	> ./dupatch

 These patches have been tested and found to work correctly in the support
 engineering environment. However, it is possible that you may experience 
 different results running these patches in your computing environment.

 HP recommends that you install these patches in a NON-Production (testing)
 computing environment to ensure there are no side-effects (due to your specific
 configurations) PRIOR to installing the patches in your production environment.

 
2 Special Instructions

SPECIAL INSTRUCTIONS for Tru64 UNIX V5.1B Patch C471.00
This temporary workaround is provided with the understanding that the 
following restrictions must be met or there may be unexpected behavior
and/or unintended operations to storage devices. Ideally applications 
should be recoded to properly use V5's multipathing environment and 
much larger B/T/L name space.

      - The system has no more than 64 SCSI buses, 8 targets
        per bus, and 8 luns per target.
      - The system has no Fibre Channel devices present.
      - The system has no SCSI-3 devices present.
      - The system has no KZPDC (Smart Array 5300) present.
      - There should be no more than one path to any storage
        device on the system.
      - The storage cables are never changed on the system.
      - No storage devices are to be hot swapped on the system.

This patch adds a hidden sysconfigtab variable, cam_limited_uagt_minor_nums,
which defaults to 0 for normal behavior.  Setting this to 1 allows
the user agent only 64 simultaneous opens maximum, but in doing
so, leaves bits <19:6> with a valid minor number.
