missing device paths
OS 11.23
i have the first drive with just a SAN based device path where as the second drive is giving all device paths.
I tried doing rmsf and recreated device paths using ioscan and insf, still it did not create all the device paths. has anyone come across such issues?
rhino1:/# ioscan -funC tape
Class I H/W Path Driver S/W State H/W Type Description
========================================================================
tape 6 0/4/2/0.45.0.255.1.3.0 stape CLAIMED DEVICE HP Ultrium 3-SCSI
/dev/rmt/c9t3d0BEST /dev/rmt/c9t3d0BESTn
/dev/rmt/c9t3d0BESTb /dev/rmt/c9t3d0BESTnb
tape 7 0/4/2/0.45.0.255.1.3.1 stape CLAIMED DEVICE HP Ultrium 3-SCSI

Re: missing device paths
1) verify you have presented the vdisks to our host
select your EVA network
select host
select presentation
do you see the disks and the lun numbers assigned
if none shows up, then
2)create a vdisk
3) select presentation
4) select the host
5) it will auto assign a lun or you can select using Assing luns.
then login to our unix
do ioscan -f
insf -e
now check ioscan -fnkCdisk
they should show up as claimed.

Re: missing device paths
Did someone create links (ln -s) from /dev/rmt/7* --> /dev/rmt/c9t3d1BEST* ?
Try this;
# rmsf -H 0/4/2/0.45.0.255.1.3.0
# rmsf -H 0/4/2/0.45.0.255.1.3.0
Check if all device files have been remove from /dev/rmt otherwise remove them by hand (rm).
# insf -eH 0/4/2/0.45.0.255.1.3.0
check output from "ioscan -fnCtape"
# insf -eH 0/4/2/0.45.0.255.1.3.0
check output from "ioscan -fnCtape" again.

Robert-Jan

Re: missing device paths
do an insf -e
/dev/rmt/c9t3d0BEST /dev/rmt/c9t3d0BESTn
/dev/rmt/c9t3d0BESTb /dev/rmt/c9t3d0BESTnb
These can be well used directly with commands as well as in scripts.
use these in assumed places like
/dev/rmt/c9t3d0BEST -- for /dev/rmt/*m
/dev/rmt/c9t3d0BESTn -- /dev/rmt/*mn
/dev/rmt/c9t3d0BESTb -- /dev/rmt/*mb
/dev/rmt/c9t3d0BESTnb -- /dev/rmt/*mnb
