ABSTRACT: ECA192 SCSI-2 DIFFERENTIAL FAST/WIDE ADAPTER MICROCODE U/D

PURPOSE:
THIS EC PROVIDES AN UPDATE TO THE SCSI-2 DIFFERENTIAL FAST/WIDE
ADAPTER MICROCODE. THIS MICROCODE CONTAINS FIXES FOR:

1) PREVENTING INTERMITTANT HANGS DURING ERROR RECOVERY ON SMP
SYSTEMS.

2) PREVENTING INTERMITTANT INTERFERENCE ON THE SCSI BUS DURING

THIS EC IS REQUIRED FOR THE SCSI-2 DIFFERENTIAL FAST/WIDE
ADAPTER (4-6) USED IN HIGH AVAILABILITY MULTI-HOST CONFIGURATION
S. IT IS REQUIRED FOR USE WITH THE SMP SYSTEMS. CURRENT LEVEL
ADAPTERS (FRU 11H7660) CONTAIN REVISION 72 MICROCODE. ECA192
CAN BE USED TO UPDATE ADAPTERS IN THE FIELD FOR USE IN THE SMP
MACHINES OR IN HIGH AVAILABILITY MULTI-HOST CONFIGURATIONS.

REVISION 72 MICROCODE IS THE MINIMUM MICROCODE LEVEL REQUIRED
FOR PROPER OPERATION OF THE IBM 7135 RAID ARRAY IN A MULTI-HOST
CONFIGURATION.

THERE IS NO REQUIREMENT FOR FIELD UPGRADES OF MICROCODE FOR THE
SCSI-2 FAST/WIDE ADAPTER (4-7) AND THE INTEGRATED SCSI-2 CON-
TROLLER ON THE 7012-380, 7012-390, 7030-3AT AND 7030-3BT.

PHYSICAL CHECK:
ECA192 IS NOT REQUIRED IF THE ADAPTER ALREADY HAS REVISION 72
MICROCODE. THE MICROCODE LEVEL MAY BE VERIFIED BY RUNNING THE
FOLLOWING COMMAND AND CHECKING THE SCSI-2 DEFFERENTIAL FAST/
WIDE ADAPTER'S VPD:

LSCFG -L ASCSI* -V | PG

FIRST, VERIFY THE FRU PART NUMBER OF THE ADPATER. ONLY P/N
65G7315, P/N52G3304 AND P/N11H3599 ARE AFFECTED BY THE EC.
THEN LOOK AT THE ROS LEVEL AND ID FIELD TO SEE IF THE REVISION
LEVEL IS 72.

ROS LEVEL AND ID ..............XX

WHERE XX WILL BE EITHER 67, 68, 70, ETC..

DETAIL:
PREREQUISITES:
DISKETTE DIAGNOSTICS VERSION 2.4.3 IS REQUIRED IF THE MICROCODE
IS TO BE DOWNLOADED TO THE BOOT ADAPTER OR IF THE CUSTOMER'S
SYSTEM DOES NOT HAVE THE DOSREAD COMMAND INSTALLED. IF THE DOWN
LOAD IS FOR NON-BOOT ADPATERS, THEN HARDFILE DIAGNOSTICS VERSION
2.4.3 CAN BE USED, PROVIDED THAT THE CUSTOMER'S SYSTEM HAS THE
DOSREAD COMMAND INSTALLED.

NOTE: IF THE SYSTEM CONSOLE IS ATTACHED TO A GXT150M ADAPTER
AND DISKETTE DIAGNOSTICS MUST BE USED, YOU MUST HAVE THE
DIAGNOSTICS 3S VERSION 1.1 DISKETTE (P/N11H3619). IF YOU
DO NOT HAVE THIS DISKETTE, DIAGNOSTICS WILL NOT RUN
PROPERLY AND YOU WILL BE UNABLE TO DOWNLOAD THE MICROCODE
ORDER P/N11H3618 IF YOU NEED THIS DISKETTE.

NOTE: AIX VERSION 4.1.2 DOES NOT SUPPORT MICROCODE UPDATES TO
SCSI BOOT ADAPTERS. IF THE CUSTOMER'S SYSTEM IS RUNNING
AIX VERSION 4.1.2 AND IS NOT SUPPORTED BY DISKETTE DIAG-
NOSTICS VERSION 2.4.3 (EX: ALL SMP SYSTEMS) ECA192 CAN-
NOT BE USED.
