HDD position change DS2405

[Goran Kubelka]

Dear All,
We have HP-UX11i OE. The HW configuration is:
HP server rp 5470 with 2 disks in mirror and HP Disk System 2405 with 4 phisical disks.
All disks in DS 2405 are in one volume group . There are 3 volumes within this volume group.
System was power down for maintaince. All hard disk drives were removed from the DS2405.Unfortunatly there was no info on disks about in wich position they were in DS 2405.Now we have to put 4 disk back but we don`t know the original position of Hard Disk Drives.Volumes contain important data!!
Any suggestions?

go through the man pages of vgimport and since all the four disk were in one volume group. Try doing vgimport using all the three disks.


Ok more more clarity, plugin all the disk in any order. and then
mkdir /dev/vggroup and then mknod /dev/vggroup/group c 64 0x0....
free minor number. And then do the vgimport and speicfy all disk you see from ioscan in HP disk system 2405

Cheers

Plugin disks in any order.

Check in ioscan -fnCdisk
mkdir /dev/vgtest
mknod /dev/vgtest/group c 64 0x020000 (assuming you free minor number - 0x020000)

vgimport -v /dev/vgtest disk1 disk2 disk3
