reading hex numbers (dev:1f026000) questions...

[James Ellis_1]

I am not sure, but this may be a hex number question. I am getting lbolt errors and I think I need to try to pvchange to change the timeout on the disks. However, the logs show

dev: 1f026000
dev_t:0X1f051200

What disks do these numbers correspond to? I attached the three files that contain the errors. I want to try to pvchange the timeouts and see if this works.

Thanks.

Hi James,

The first one is
c2t6d0
and the second is
c5t1d2

c=first 2 digits after 1f in hex
t=next digit after c
d=next digit after t

HTH,
Jeff

The 1f in the number indicates the disk driver

The 0260 is the portion you want to look at.

The 02 is the controller, in this case 2
The 6 the is the target
And the 0 is the device

In this case that is referenceing /dev/dsk/c2t6d0.

You could also do an

# ll /dev/dsk | grep 026000

And that would get you the appropriate disk.

The other way to approach this on your system is to do:

ll /dev/rdsk | grep

SO

ll /dev/rdsk | grep 26000

and

ll /dev/rdsk | grep 51200
