mksysb restoration

[bonsky]

guys,
i remember i read this one but unfortunately cant find the thread again. anyways, Can somebody help me on this,
I have a mksysb from a mirrored OS then i want to restore the mksysb to another server which does have enough disk space so i want to take out the mirroring from the mksysb? So, how do i go about the procedure of editing the image.data from the tape? thanks a lot...

Hi Bonsky,
1) On mirrored machine run mkszfile. This will create a new
/image.data file.

2) Edit the /image.data file. In each lv_data stanza
change the number of copies to 1 and number of PPs
to the same number as the LPs.

Example:
Before:

lv_data:
VOLUME_GROUP= rootvg
LV_SOURCE_DISK_LIST= hdisk0
LV_IDENTIFIER= 00000001113f3c62.5
LOGICAL_VOLUME= hd2
VG_STAT= active/complete
TYPE= jfs
MAX_LPS= 512
--> COPIES = 2
LPs = 70
STALE_PPs= 0
INTER_POLICY= minimum
INTRA_POLICY= center
MOUNT_POINT= /usr
MIRROR_WRITE_CONSISTENCY= on
LV_SEPARATE_PV= yes
PERMISSION= read/write
LV_STATE= opened/syncd
WRITE_VERIFY= off
PP_SIZE= 4
SCHED_POLICY= parallel
--> PP = 140
BB_POLICY= relocatable
RELOCATABLE= yes
UPPER_BOUND= 32
LABEL= /usr
MAPFILE=
LV_MIN_LPS= 68

After:

lv_data:
VOLUME_GROUP= rootvg
LV_SOURCE_DISK_LIST= hdisk0
LV_IDENTIFIER= 00000001113f3c62.5
LOGICAL_VOLUME= hd2
VG_STAT= active/complete
TYPE= jfs
MAX_LPS= 512
--> COPIES = 1
LPs = 70
STALE_PPs= 0
INTER_POLICY= minimum
INTRA_POLICY= center
MOUNT_POINT= /usr
MIRROR_WRITE_CONSISTENCY= on
LV_SEPARATE_PV= yes
PERMISSION= read/write
LV_STATE= opened/syncd
WRITE_VERIFY= off
PP_SIZE= 4
SCHED_POLICY= parallel
--> PP = 70
BB_POLICY= relocatable
RELOCATABLE= yes
UPPER_BOUND= 32
LABEL= /usr
MAPFILE=
LV_MIN_LPS= 68

3) Make a new mksysb image. Do not use the -i or -m options.

4) On mirrored machine run mkszfile to restore /image.data.

5) install not mirrored machine.

Regards Boris
