Changeable SCSI Disk Boot Messages
Last modified: 2009-05-01 12:13:14 EDT
Description of problem:
Sometimes, I have seen SCSI disk boot messages have been changed among different boots with the same Kernel,
SCSI device sdc: drive cache: write through
Attached scsi disk sdc at scsi0, channel 0, id 2, lun 0
- Vendor: IBM Model: 26K4888a S320 1 Rev: 1
+ Vendor: SDR Model: GEM318P Rev: 1
Type: Processor ANSI SCSI revision: 02
Fusion MPT SAS Host driver 3.12.19.00rh
libata version 2.00 loaded.
Version-Release number of selected component (if applicable):
occasionally (1 in 10 boots?)
Don't know if this is a regression, but I could not reproduce the issue for RHEL 4.6 GA Kernel (2.6.9-78.EL) for rebooting around 20 times.
I could reproduce it with kernel-2.6.9-78.0.3.EL. Let me run it for a longer period to see if it is there since RHEL 4.7.
Any idea on why would these information would change? Is it because there are two disks in the controller, and one of them has been picked up randomly?
We need to know full h/w configuration for SCSI bus, may be there is some kind of collision. I'll ask RHTS admins.
The machine iin question (groucho.rhts.bos.redhat.com) is broken at the moment.
I'll close this out for now, and I can reopen this if have seen another occurrence in the future.
