vg changing controlers

Joseph C. Denman — Wed, 11 Apr 2001 12:40:14 GMT

I believe I know the answer, but I wanted to put a post just for a warm fuzzy.

Whats going on:

K460 with 3 Jamacia boxs. The Jamacia boxes have about 6 Drives in each. We are upgrading the K460 to a K580. The hardware path of one of the jamacia boxes is going to change. What is the easiest, most painless, way to get the vg ported over to the new controler?

NO MIRRORS. HFS filesystems.

use the ioinit command. See man page for it, in the examples section is how to reassign an instance number to a card, this way you can retain your c1,c2,c3... instance numbers for your drives when you change hardware. Very handy.

hi,
check vgexport/vgimport.
-vgexport the VG
-move the drive(s)
-create device files for VG
-vgimport the VG

good luck,
Thierry

Hi Joesph:

Use vgexport/vgimport. See the man pages for both for more information.

On the "outgoing side":

# vgexport -p -v -s -m /tmp/vgXY.mapfile /dev/vgXY

...and on the "incoming side"...

# mkdir /dev/vgXY
# mknod /dev/vgXY/group c 64 0xXY0000
# vgimport -s -m /tmp/vgXY.mapfile vgXY
# vgchange -a y vgXY
# vgcfgbackup vgXY

...JRF...
