I need to make a backup of a vg in node A and activate the snapshoot lvol's in node B.
Could you help me?

thanks in advances

Hi,

Check fbackup / frecover
Or you could vgexport the volumegroup on node A pull out the disks and import it on node B ( vgimport or vgscan command)

Hi Roberto,

it depends which vg you want to backup.

generally you could use make_tape_recovery:

make_tape_recovery -a /dev/rmt/0mn -A -v -x inc_entire=vg01 (will backup vg00 + vg01 on norewind dev, for excluding lvols can use
"-x exclude=PATH option, for test without data writing on tape you can use -p option)

on the target box interrupt boot process and search for boot dev:

sea ipl and boot

boot PATH

rgds Jan

boot

Does this vg live on a SAN that both nodes have access to?

Is this going to be a permanent copy, one-time temporary image, daily snapshot, etc?

The answers to these questions may help determine what options you have and what would work best.

Hi,

you could vgexport the volumegroup on node A and import it on node B :

ON Node A :
umount /fsxx
vgchange -a n vg01
vgexport -m /tmp/vg01.map -s vg01
ftp /tmp/vg01.map
On Node B :
mknod /dev/vg01/group -c 64 0x010000
vgimport -m /tmp/vg01.map -s vg01
vgchange -a y vgxx
modify /etc/fstab
mount -a

1. Copy across the LAN the "cpio" way:

cd $sourcedir
find . -xdev -depth | cpio -ocax | \
remsh $destcpu "cd $destdir ; cpio -icduxm"

where: sourcedir and destdir both exist.

2. Both servers are connected at 1000 BT Full Duplex. GigE switch, copper.

3. EMC disks. 1 GB/s switch.

4. Timing:
a. A single copy copies at the rate of 19 GB/hr.

hi all:

node A:
vg01 in disks of nike FC30 Galaxy
node B:
vg01 in disks of IBM 2105F20

The task is connect disk of IBM 2105F20 at node A, mirroring vg01, disconect disks of node A, conect disks at node B and active the vg01.

node A will be backup of node B, node B will be in production.


best regards

Hi Mr. Roberto,

Use 'vgcfgbackup' & 'vgcfgrestore'. See the man page for details option.

Hope this information can help you.

Merry Xmas & Happy New Year.
