 ENV:           CWS = 4.2.1 (mca/up)    node = 4.1.5 (high)
                sysback 3.3.3.17

*CUSTOMER REP:  Kevin McNamara

 PROBLEM:       Changed pp size
                Restoring 4.1.5 image from CWS and then will migrate
                restore failed during getrootfs after install

*ACTION TAKEN:  Looks like version conflict without warning.
                Will have cust boot from a 4.1.5 machine then restore
                 from the local cws images.
                Still on call

*ACTION PLAN:   If this fails, will type "DEBUG" at main screen and
                 analyze debug output in /tmp/debug.out
                If this fails due to space, will increase ramfs in
                 /usr/sbin/mkboottape.4 from 16384 to 18432 and will
                 remake boot image.

                Checked a bunch of items and spoke with JAD and BC
                looks like the LED before the 888 indicates the problems
                Cust looked up sequence:
                888 = crash
                102 = system halt
                700 = software interrupt
                0c8 = dump device not configured
                Had cust reboot from 4.1.5 machine again and watch LED
                bootp -> device config -> c31 -> please define the sys-
                tem console...  press "1" -> LED c33 -> "AIX SYSTE "
                HANG 888-102-700-0c8

 PROBLEM:
Sysback restore fails
*ACTION TAKEN:

Customer is using a 4.1 node as sysback boot install server.

Node is crashing when sysback is started

Customer feels he is missing  device drivers 

Conferenced in Mark Moody (B/E)

We can run spmon -open node\# on the node we made the sysback image Ok.
This shows the B/I server has all the required software for a tty .

Customer found tag in sysback manual about using newer versions
of sysback for restore. Customer appears to be doing everything correctly.

System hangs when /usr is mounted from ram.

Need to talk to Josh Davis in sysback. Josh will be in at 9AM.

WE feel this is a aix or sysback problem. The tty is opening OK.

Customer to go off-line, we\\ll conference with Josh when he arrives, then
call customer back

*ACTION PLAN:
Wait for Josh/Lee for conference.

 TEST CASE:
N/A


Response:

Customer called back.  JR is researching.  Will call customer back
at 1-800-SKY-PAGE pin 5347287.

Response:

*CUSTOMER REP:  N/A

*ACTION TAKEN:
                Spoke with John Rigler.
                Turns out that in his version of sysback, during
                 the rc.boot, all of his local tape devices are
                 configured with cfgsctape, rather than checking for
                 the proper config method.  Since customer has 3590's,
                 the proper method would be cfgatape.
                John had customer modify rc.boot in sysback dir and
                 rebuild the boot image.
                Aparently, all was well until some vg data was restored
                 to improper locations.
                John will update further.

*ACTION PLAN:   Leaving with John.

Response:

Here is the code that gets run where this is failing:

        \# Ensure that all tape drives are
        \# configured to block size 512.
        lsdev -Cc tape | while read tapename dummy
        do
                ucfgdevice -l $tapename
                chggen -l $tapename -a block_size=512
                cfgsctape -l $tapename
        done

This is later changed to work with Atape devices, 'cfgsctape' is the configuration method
for alot of standard tape drives, but none of the Atape drives.  This is fixed at version
4, but the problem we have is that even though we aren't using the local drives, this 
still fails.

Response:

Closing with Customer Approval
