TITLE: OpenVMS VMS73_FIBRE_SCSI-V0100 Alpha V7.3 FibreChannel/SCSI ECO Summary
 
New Kit Date : 20-AUG-2001
Modification Date: Not Applicable
Modification Type: New Kit

NOTE: An OpenVMS saveset or PCSI installation file is stored
       on the Internet in a self-expanding compressed file.
 
       For OpenVMS savesets, the name of the compressed saveset
       file will be kit_name.a-dcx_vaxexe for OpenVMS VAX or
       kit_name.a-dcx_axpexe for OpenVMS Alpha. Once the OpenVMS
       saveset is copied to your system, expand the compressed
       saveset by typing RUN kitname.dcx_vaxexe or kitname.dcx_alpexe.
 
       For PCSI files, once the PCSI file is copied to your system,
       rename the PCSI file to kitname-dcx_axpexe.pcsi, then it can
       be expanded by typing RUN kitname-dcx_axpexe.pcsi. The resultant
       file will be the PCSI installation file which can be used to install
       the ECO.

ECO KIT SUMMARY:

An ECO kit exists for FibreChannel and SCSI Drivers on OpenVMS Alpha
V7.3. This kit addresses the following problems:

NEW FUNCTIONALITY INTRODUCED IN VMS73_FIBRE_SCSI-V0100 KIT:

  o This kit provides support for the KZPEA-DB Ultra 160 SCSI
     Storage Adapter.

     The Compaq KZPEA-DB SCSI Storage Adapter is a high-performance
     dual channel Ultra 160 SCSI adapter that connects external or
     internal SCSI storage devices to a PCI-based host Alpha
     system. The module provides multimode SCSI support for both
     Single-Ended (SE) and Low Voltage Differential (LVD) SCSI
     peripherals in a 33/66 Mhz PCI slot.

     The KZPEA adapter has the following features:

         o Provides full-featured dual-channel Ultra 160 SCSI host
            adapter with a 66/33 Mhz 64-bit PCI interface.

         o Supports Ultra160 data transfer rates up to 160 MB/sec on
            the 16-bit SCSI bus using LVD SCSI peripherals.

         o Supports mixed SCSI-2, Ultra2, and Ultra160 SCSI
            peripherals on Compaq Storageworks enclosures.

         o Supports hot-swapping/hot-adding of SCSI peripherals.

         Images Affected: [SYS$LDR]SYS$PKADRIVER.EXE

PROBLEMS ADDRESSED IN VMS73_FIBRE_SCSI-V0100 KIT:

  o The system can hang due to IO's Timing Out, and the
     driver not re-trying the IO command. The IO timeout can
     be detected through the error log.

         Images Affected: [SYS$LDR]SYS$PKADRIVER.EXE

  o The KZPEA SCSI adapter is seen as a disk and not a
     device.

         Images Affected: [SYS$LDR]SYS$PKADRIVER.EXE

  o When an HSZ/HSG device reports mirror copy status events,
     the ERRCNT of the device is incremented. This gives the
     false impression that there is a problem with the
     device(s).

         Images Affected: [SYS$LDR]SYS$DKDRIVER.EXE

  o MountVerifyTimeouts do resets during heavy IO's.

         Images Affected: [SYS$LDR]SYS$PKADRIVER.EXE

  o Add device recognition for the 7892 SCSI Adapter.

         Images Affected: [SYS$LDR]SYS$PKADRIVER.EXE

  o Exception conditions, such as those resulting from power
     surges, disk errors or AUTOGEN operations, can produce
     hangs, crashes or data corruption in an SMP environment.

         Images Affected: [SYS$LDR]SYS$PKWDRIVER.EXE

  o Tape drive performance degrades significantly after a
     tape error.

         Images Affected: [SYS$LDR]SYS$MKDRIVER.EXE

  o Odd byte records read from tape to a memory buffer larger
     than the tape record results in one extra byte of data.

         Images Affected: [SYS$LDR]SYS$PKWDRIVER.EXE

  o Performance degrades after a bus reset.

         Images Affected: [SYS$LDR]SYS$PKADRIVER.EXE

  o A Target negotiates a speed it can't support.

         Images Affected: [SYS$LDR]SYS$PKADRIVER.EXE

  o The Emulex FibreChannel adapters support a feature called
     Interrupt & Response Coalescing which can significantly
     reduce the number of host interrupts the adapter
     generates. To enable this feature the driver must pass a
     response count and a delay in milliseconds to the adapter
     when it configures the FibreChannel link. This causes
     the adapter to defer interrupting the host until it has
     accumulated the requested number of responses or until
     the specified amount of time has passed, whichever occurs
     first. The feature has the added benefit of making each
     interrupt more cost-effective by driving up the average
     number of responses processed for each one.

     This kit adds SYS$ETC:FC$CP.EXE, an application which a
     privileged user can run to enable Interrupt & Response
     Coalescing, and a $QIO API to SYS$FGEDRIVER to handle the
     $QIO request.

         Images Affected: [SYS$LDR]SYS$FGEDRIVER.EXE

  o An f$getdvi ("tape","mt3_density") command does not show
     compaction correctly.

         Images Affected: [SYS$LDR]SYS$MKDRIVER.EXE

  o If a disk is mounted software write protected, when the
     disk enters and completes mount verification, the disk is
     software write enabled.

         Images Affected: [SYS$LDR]SYS$DKDRIVER.EXE

  o KZPEA takes too long to reconfigure hot-swapped disks

         Images Affected: [SYS$LDR]SYS$PKADRIVER.EXE

  o A system can experience CPUSPINWAIT Crashes. See Crash
     dump summary below.

INSTALLATION NOTES:

This kit requires a system reboot. Compaq strongly recommends
that a reboot is performed immediately after kit installation
to avoid system instability

If you have other nodes in your OpenVMS cluster, they must
also be rebooted in order to make use of the new image(s). If
it is not possible or convenient to reboot the entire cluster
at this time, a rolling re-boot may be performed.

INSTALLATION INSTRUCTION:

Install this kit with the {Installation Utility} utility by
logging into the SYSTEM account, and typing the following at
the DCL prompt:

PRODUCT INSTALL VMS73_FIBRE_SCSI /SOURCE=[location of Kit]

The kit location may be a tape drive, CD, or a disk directory that
contains the kit.

Additional help on installing PCSI kits can be found by typing
HELP PRODUCT INSTALL at the system prompt
