determine disk controllers

How do I determine the # of disk controllers I have? (I imagine they s/b in the ioscan - but not sure as to what they are referred to). Also - will there be any 32/64 bit issues with these controllers when we upgrade our HP9000 K360 from o/s 10.20 (32 bit) to b.11.11 (64 bit). Thanks for your help.

Re: determine disk controllers

You can run the command:

# ioscan -fnkC ctl and that will give you something like:

Class I H/W Path Driver S/W State H/W Type Description
======================================================================
ctl 0 10/0.7.0 sctl CLAIMED DEVICE Initiator
/dev/rscsi/c0t7d0
ctl 1 10/12/5.7.0 sctl CLAIMED DEVICE Initiator
/dev/rscsi/c2t7d0

(sorry if the formatting gets messed up)

You can then run # ioscan -fk to show all devices and go back and see what the controller is listed as.

For instance 10/0.7.0 is the initiator for the following:
ext_bus 0 10/0 c720 CLAIMED INTERFACE GSC built-in Fast/Wide SCSI Interface

As far as the cards go: Any cards will be either HP-PB or HSC and I am not aware of any problems with them going from 10.20 to 11.x.

Re: determine disk controllers

Hi Byran

ioscan -fk | grep SCSI will give you the scsi controllers ,

sam--->peripheral devices ---> cards will give you the list of cards


stm or xstm will also give you the controllers ,

There is no drive available for PCI cards on HPUX 64 bit , so if u have a 100mbps pci controller that wont work , we used the default 10mbps as we were not using that for a production machine.

Re: determine disk controllers

thanks. ok then - how do I determine what controllers are responsible for what disks or volume groups?

Re: determine disk controllers

Hi Bryan,

Run ioscan again thusly

ioscan -fnC disk

Then compare the HW path of the ctrlr to the disks. The disks that have the same starting path as the ctrlr are under that ctrlr.

HTH,
Jeff

Re: determine disk controllers

Hi

ioscan -fnCdisk > /tmp/test
ioscan -fnCctl >> /tmp/test
sort +2 test

the output will have the disks with the controllers in order.
