"ssaencl -l enclosure0 -d" output

[ogniemi]

Hello,
I have a problem with one bay in SSA enclosure D40.
Having a disk put in the 7th bay, the only lighting led on the disk is orange one. "cfgmgr -l ssar" doesn't configure disk in the system. I thought the disk is broken, but when IBM put new one the same problem occures. Besides, having the disk in the bay it doesn't close the SSA loop. After inserting dummy device, the loop was not closed as well (the disk is in 7th bay and leds of 6th and 8th disks indicated open loop).

The status of bays 6, 7, 8 when disk is present in the 7th bay:

enclosure enclosure0
component drive_bay_6
contents disk_drive
fault FALSE
exchanged FALSE
PFA FALSE
identify FALSE
remove FALSE

enclosure enclosure0
component drive_bay_7
fault FALSE
exchanged TRUE
PFA FALSE
identify FALSE
remove TRUE

enclosure enclosure0
component drive_bay_8
contents disk_drive
fault FALSE
exchanged FALSE
PFA FALSE
identify FALSE
remove FALSE


The status of bays 6, 7, 8 when dummy device is present in the 7th bay:

enclosure enclosure0
component drive_bay_6
contents disk_drive
fault TRUE
exchanged FALSE
PFA FALSE
identify FALSE
remove FALSE

enclosure enclosure0
component drive_bay_7
contents dummy

enclosure enclosure0
component drive_bay_8
contents disk_drive
fault TRUE
exchanged FALSE
PFA FALSE
identify FALSE
remove FALSE

The dummy device is recognized but neighbour disks have "fault TRUE" - the SSA loop is really not closed.


Can anyone explain what does mean "exchanged TRUE" and "remove TRUE" ??? (the disk cannot be discovered and the orange led is lighting on the disk)

And can anyone say something more about "ssaencl" switch "-S"?

===========================================================
-S Resets the “exchanged” flag of the selected FRU.
-S d[drive_bay ...]
Resets the flag for the selected drive bay. Valid values for drive_bay are 1, 2,
3, and so on.
-S b[card ...]
Resets the flag for the bypass card. Valid values for card are 1, 4, 5, 8, 9, 12,
13, 16.
-S p[PSU ...]
Resets the flag for the selected PSU. Valid values for PSU are 1, 2.
-S r Resets the flag for the remote power-on control (RPO).
-S c Resets the flag for the controller card.
-S o Resets the flag for the operator panel.
============================================================

We are going to replace whole drawer but maybe it is not necessary and somone of you knows other solution.

hi ,

how have you cabled your SSA ?
have you just got one loop e.g. A1 into port 1 on ssa cab
out of port 8 from ssa cab into a2 on ssa card ?
how many SSA cards have you got installed ?
have you got any lights flashing on the ssa card links ?

cabling is not a problem - everything was fine for about 5 months till yesterday when system reported pdisk problem (ssa disk ERR4) - it says disk is damaged and should be replaced with new one (disk went in Defined status and was not reachable). As I told previously, replacing disk didn't help - the same status of disk led, no hdisk configured after running of cfgmgr.

and the loop is very simple, just blue SSA cables going through 2 SSA adapters in the machine to SSA enclosure's J5 and J8.

so,
7133.D40.J5-SSA0.A1-SSA0.A2-SSA1.A1-SSA1.A2-7133.D40.J8


regards,m.

faulty backplane. IBM must replace it. good luck.
