how to remove the added disk from unix system and return back to eva

[Sajjad Sahir]

I added one disk in my node1
and node2 from eva both have same lun number 7
my disk is c0t13d6
after that i created physical volume in both node
and created vggroup and logical volume now i want to remove these logical volume and volume group
after that i want to remove disk from my unix itself and back to eva.

Running vgexport will get rid of the LVM info. Then you need to reverse the procedure used to present the LUN. Sorry I can't be more specific, I've never worked with eva.

Sajjiad,

vgexport /dev/vgxx, it will remove the disk and then from EVA, you can remove the vdisk from your commandview.

hope this help

Hi sajjad,
1) If you created vg,1st deactivate it with the command:
# vgchange -a n vgname.
2) Then expot the vg-:
# vgexport vgname.
This will delete the vg and update LVM information.
3) # ioscan -fnC disk :-This will give the disk information which you have presented from EVA.
4) # rmsf -H hardware path of the disk.
5) go to cmdview eva -
vdisk >unpresent the vdisk
And delete the vdisk.

Rgrds,
Davis Paul.
