Re: vdisk h/w path is not detected

If you see 7 disks but not 8, there is most likely a problem with host mode.

Make sure you present vdisks in HP-UX mode in command view!!!

Hope this helps!
Regards
Torsten.

Re: vdisk h/w path is not detected

Hi,

Can you try by assigning one more 300GB LUN to the system and check it sees there. If so, please increase the size by 50Gb and represent. The lun to be there unless there is a LUN size limitation, not sure though.

#insf -eC disk

all the time and check.

Re: vdisk h/w path is not detected

Hi All,

There is a autopath problem in the host level only because for testing again i created another vdisk of size 1gb at EVA and presented vdisk to this host. At this host end i executed ioscan command and it is not detecting. I don't now what is the problem.
Previous this was worked properly, i created device files, vg, lv and filesystem also.

Can anyone help me what will be the reason?

Make sure all vdisks are presented in

"Hewlett-Packard HP-UX" mode!

Hope this helps!
