For the SCSI PCI RAID Adapters on the Patent Server's 7024-F40's:

 ------------------------------------------------
 Q.  I have installed the SCSI-2 F/W PCI RAID Adapter and have
     connected hard files to it, but the hard files are not shown
     as hdisks.  How can I see the hard files ?

 A.  The SCSI-2 F/W PCI RAID Adapter is not a plain SCSI Adapter,
     it's a  *RAID* Adapter.  The physical disks must be combined
     into disk arrays before the operation system will see them
     as a single hdisk.  See SCSI-2 F/W RAID Adapter Reference
     Guide, pub SC23-1889-00.
 -------------------------------------------------
 Q.  I have just added one or more hot pluggable hard files, but
     the SMIT option List all PCI SCSI RAID Drives doesn't show
     the new drives unless I reboot.  Is there any way to have
     the adapter scan for drives, like cfgmgr scans for devices
     so I don't have to reboot ?

 A.  To add a spare drive without rebooting, you must use the
     option " Add Spare Drive " in the PCI SCSI Disk Array Mgr
     in SMIT.  This process is documented in the SCSI-2 F/W
     RAID Adapter Reference Guide.  Add a Spare Drive 3-8.
 --------------------------------------------------
 Q.  When I remove physical disks for one hdisk, the other hdisks
     created by the adapter will not function, even though
     none of the disks removed were part of the other hdisks.
     How can I access the other hdisks ?

 A. Removing the physical disks created an invalid configuration.
    the adapter does not maintain separate configurations for
    each hdisk, only for the entire adapter.  The correct
    procedure for removing disks that are part of an array is in
    the SCSI-2 F/W PCI Adapter Reference Guide.  This document
    explains how to synchronize an invalid configuration.
    See:

     Revoving a Disk Array  3-11
     Configuration Synchronization  3-15

From RETAIN Tip # H162626,

This ECA updates the device driver and microcode of the SCSI-2
F/W PCI RAID Adapter to prevent a variety of soft errors, per-
formance problems, and stability issues. The Device Driver
installation is a CUSTOMER RESPONSIBILITY.
This ECA effects 7024-E30, 7025-F40 or F50, 7026-H10, 7013-S70
7015-S70 or 7017-S70..
The device driver MUST be installed first, then followed by the
microcode. There is one microcode diskette and one device driver
diskette for each level of supported AIX. The supported levels
of AIX are 4.1.5, 4.2.1, and 4.3.
   To determine if one or more SCSI-2 F/W PCI RAID adapters are
installed, enter the command; lsdev -Cs PCI | grep scraid..
The adapter names will be "scraidx", where "x" is 0,1, or some
other number.
   To check the microcode level, enter the command;
 lscfg -vl scraidx
   If the "Loadable Microcode Level is less than 97308, then you
should apply this ECA..

   The PCI SCSI-2 F/W RAID adapter diagnostics as orginally
released will not allow microcode to be downloaded to drives
that have been assigned to an array.  Microcode can oly be
downloaded to drives that are spares or hot-spares.  Several
APAR's have been released to address this problem. They are:
   AIX 4.1.5 -- IX73626, IX75111, IX75126
   AIX 4.2.1 -- IX73630, IX75477, IX75478
   AIX 4.3   -- IX73632, IX75295, IX75269
   --- NOTE IX75295 & IX75269 will be available approx. 4/30/98

Order this ECA through the normal ECA process or download it
from AIXTOOLS as package SCRAID4.
