rp2470

I have a old rp2470 that is having internal disk issues. I want to check if itтАЩs a disk or controller problem. What utility can I run to determine if I have a bad disk or controller ?

Thanks in advance

Re: rp2470

Define "internal disk issues". Any actual
error messages, log entries, symptoms, ...?

How many disks are on this controller?
How many disks on this controller are
affected?

If only one disk is affected, then I'd
probably try replacing the disk.

It's not clear to me that any "utility" could
reliably locate a hardware problem of this
kind. What if the cable is bad? Would that
be a bad disk or a bad controller?

Re: rp2470

hi,

the rp2470 can only have 2 internal disks in the actual server and both are on the same controller.

how many disks are installed? if two, is the problem affecting both disks or just one? its most likely the disk that has trouble in my opinion, but some error messages or bits from the syslog or ems logs would help.

you should have STM installed so try and run some tools on the disk, exercise and infolog tool. just make sure you only do a read test on the disk.

Is this your root disk? and is it mirrored?

of you dont have stm then you could do a quick dd command possibly on the disk.

It might be also worth checking the bdf output too? but depends why you think you have a bad disk or controller

Stephen,

> What utility can I run to determine if I have a bad disk or controller ?

- find the disk in ioscan :
# ioscan -fnC disk

- It should be in CLAIMED state.

- Run diskinfo:
# diskinfo /dev/rdsk/c?t?d?

- check syslog and dmesgae for any error like scsi lbolt, etc.
# cat /var/adm/syslog/syslog.log | grep -i -e vxfs -e lbolt -e scsi -e vxfs


- check cstm for any read /write error:
# /usr/sbin/cstm
---map
---select the disk
---info
---infolog


- To check the controllers,
# ioscan -fnC ext_bus
--should be in clamed state.


-Finally if there is any hardware error it will reflect in the syslog.log and dmesg: so keep monitoring it.
Additionally you can check /var/opt/resmon/event.log for EMS Hardware Monitoring alert messages.


Cheers,
Raj.

Andrew: the rp2470 can only have 2 internal disks in the actual server and both are on the same controller.



No.
The upper disk (0/0/1/1.15) is on a separate bus of a dual channel chip, the other channel is the external LVD connector, the lower disk (0/0/2/1.15) is on a separate bus too, the second channel of this second chip is the external single ended connector.

Hope this helps!

Torsten.
