scsimgr brings error on hpux11.31

[Marko Vidoz]

Hi all,

I have installed an rx6600 with hpux 11iv3 in an eva 8000 fabric.
After installing scsimgr worked fine but now scsimgr doesn't work:
eg: scsimgr -v get_info -d esdisk -D all_lun

brings:
scsimgr:ERROR: Cannot open SCSI stack management device special file: /dev/escsi
No such device or address

I have checked the character device file /dev/escsi with other nodes, but everything seems to be ok (major, minor numbers)

Any Idea?

Many thanks.

You checked the major and minor numbers, but did you cross reference that against the output of "lsdev"?

Perhaps the wrong driver is assigned to your "/dev/escsi" device file.

Hi,
I checked the reference:
root@eds-clus1-n1:/etc/cmcluster> scsimgr lun_map
scsimgr: ERROR: Cannot open management device file '/dev/escsi': No such device or address

root@eds-clus1-n1:/etc/cmcluster> scsimgr -v get_info -d esdisk -D all_lun
scsimgr:ERROR: Cannot open SCSI stack management device special file: /dev/escsi
No such device or address


root@eds-clus1-n1:/etc/cmcluster> ls -l /dev/escsi
crw-r--r-- 1 bin bin 21 0xffffff Jul 17 19:25 /dev/escsi

root@eds-clus1-n1:/etc/cmcluster> lsdev -C disk

Have you tried recreating the device manually using "mknod"? Or better yet, use "rmsf" to remove this file, and then try using "insf -e" to force the recreation of missing device files according to the system.

Just a speculation, but maybe the "spt" (scsi pass-thru driver) is needed too? Maybe compare the driver listings with this host against the other "workings" hosts you have and perhaps the problem will reveal itself.
