Using sam to manage EMC disks

[tirititraun]

Hi guys,

I have a 11i HPUX box. Running a ioscan -fnCdisks, I can see my clariion disks with its device file, even running powermt display dev=all I can see everything, but...using sam, I can see only ono HW path with 24 paths. No disks at all.
Any ideas??
Thanks a lot
JOse

[tirititraun]

I meant "one". I´m gathering all the info. I´ll post it asap
thanks a lot

hmmm... ok.

Run SAM and select Disks > File Systems > Actions > Diagnose Missing Disks.
When this has completed, exit the window and the previous window and re-enter the Disks and File Systems option. The LUNs should now be visible.

 

[tirititraun]

Thanks, but I´m sorry it doesn´t work. We have tried this but no results
thanks a lot

[Chacalinc]

hmmm.. gosh.

SAM creates a temporary device file /dev/dsk/disk_query for info gathering purposes, how does this file looks like?

file /dev/dsk/disk_query
more /dev/dsk/disk_query
strings /dev/dsk/disk_query

 

[Chacalinc]

another tray is to remove the device file with "rmfs" and then recreate it with "insf"..

did you try it?

 

[Chacalinc]

sorry. command should be "rmsf

It looks like sam is unable to display disks. i haven´t tried to remove and recreate...i´ll try

Thanks
Jose

 

[Chacalinc]

one more question, can you create a volume group manually? I mean with pvcreate, vgcreate, etc..

 

[tirititraun]

hi there,
sorry for the delay.
I can manage disks properly with lvm commands. It´s only with sam that I can´t see the disks...
thanks a lot

Jose
