at present all all six disks are identified as AIX system disks, is this a problem????

or if anyone knows where there is a diagrams on the net please let me know. its a 6 port backplane internally on a F50 . Thanks for all your help so far, your time has been appricated

bi - youve hit the nail on the head there. if i look in lscfg I can see all six disks but when i go to smit - devices - ssa raid arrays - and try to create or view i can never see any disks, what cabling could be wrong , ive checked it a few times.

Have 6 disks in a 6 bay , so they are all populated yes 1 loop two cables I do get an error up on screen ssa1 SRN 45202 IBM SSA 160 Serial Raid Adapter 14109100 any ideas what this could be, not hardware fault cause ive just changed the ssa card itself

if i do Advanced Diagnostics Routines / System verification A PROBLEM WAS DETECTED 45302 100% SSA-SUBSYSTEM 30-60 Any idea what this code means , loooked through my paper work mbut to no avail

yes it is, have you got scsi drives aswell or just SSA, i have both. Any ideas

just noticed something, you say loops can be made from 1-4 and 1-8 , would this cause this problem , I have 6 disks with no dummys, the bay and backplane only hold 6 disks. How can I check this???

The backplane is wired as follows J6 - j12 backplane j5 - J11 Backplane B-1 J13 - J14 Backplane J12 - J13 Backplane B2 The light on the ssa card channels b1 b2 is constantly on.

i was just going to try increasing the scatter gather table size , 8 at present , but im probably just clutching at straws at the mo

do you mean on the ssa card itself or on the backplane ? I will open her up and have a look if you let me know

Basic question I know but im kinda new to AIX, i want to make a change to the SSA adapter but i cant because its in use, how do i stop the adapter and then restart it when ive made my changes

Also have reinstalled the drivers and microcodes for drives and adapters, no change. In diag - Link speed - Reads : Speed Destination ssa0:B1 20 pdisk2 pdisk2 20 pdisk1 pdisk1 20...
