Help with Solaris 8

UNIX Solaris

Good Morning All,

We are having a Sparc server v880 running Solaris 8 and recently we ran into a strange issue as below

Jan 20 15:24:16 xxxx scsi: WARNING: /pci@9,700000/scsi@3 (glm1): 
Jan 20 15:24:16 xxxx        Connected command timeout for Target 0.0 
Jan 20 15:24:16 xxxx scsi: WARNING: /pci@9,700000/scsi@3 (glm1): 
Jan 20 15:24:16 xxxx        got SCSI bus reset 
Jan 20 15:24:17 xxxx scsi: WARNING: /pci@9,700000/scsi@3,1 (glm2): 
Jan 20 15:24:17 xxxx        Connected command timeout for Target 0.0 
Jan 20 15:24:17 xxxx scsi: WARNING: /pci@9,700000/scsi@3,1 (glm2): 
Jan 20 15:24:17 xxxx        got SCSI bus reset

Because of above error when the commands like format, devfsadm, cfgadm, iostat are issue nothing comes up and doesn't return the prompt back.

Not sure what is this glm1 and glm2 are here. This is a stand alone server no tape or juke box attached to them.

Any ideas will be great for fixing this and please let me know if any more information needed?

Thanks,
P

I would say the disk /pci@9,700000/scsi@3,1 is about to die...

3

None of the disk are on it. At the end it says glm1 and glm2

All my disks are on /pci@8,600000/

4

Is GLM something to do with a fibre card? Gigabit Link Module

Do you have any open-ended fibre links or decommissioned fibre links?

Should be a card in PCI slot 5. Would also say a fibre card with connection to external storage (or not anymore in this case).

Seems like it Duke. After bang my head and running probe-scsi-all from OK prompt somehow that error isnt showing up now but ran into different issue on same server

Look at the below output of cfgadm , I understand pcisch0:hpc1_slot0 stuff if related to tape drives.

bash-2.03# cfgadm -al

I cant see c1 controller in above stuff, where as all the disk are using c1 controller.

How can this be ? Am I missing anything

Thanks,

Try to run devfsadm -Cv to get rid of device entries that are not used anymore.

It could be a poor contact on an add-in card. I would power down, pull out each add-in card, and plug it back in again just to make sure the edge contacts are making. Perhaps this machine has been around a while and card(s) need reseating.

I tried doing it but see see the same output of cfgadm -al as sent before and still no C1 controller in the list

Whenever i reboot the server glm issue pops up then none of the commands work but after couple of hours glm issue disappears and commands starts tot work

Thanks,
P

Under normal circumstances no system will change its behaviour i.e., commands which don't work just start working after a couple of hours of running. There are only so many things that can cause it.

  1. The system is running something at boot time which is time-based and toggling off something for a couple of hours.
  2. A peripheral system is toggling something for a couple of hours e.g. a SAN is making volumes unavailable at certain times.
  3. Or most likely it is a hardware problem e.g. as the system heats up things start working, see my post#8.
