Dear Sudhaadm,

do # pvcreate
then # vgextend
then # lvextend
and #extendfs

Please check the man pages for further info.

With Regards,

Siva.

hi,

try this:

# vgextend /dev/vg1 /dev/dsk/c10t6d6 /dev/dsk/c10t6d7

with online:
# lvextend -l /dev/vg1/
# fsadm -F vxfs -b

without online:
# lvextend -l /dev/vg1/
# umount /dev/vg1/
# extendfs /dev/vg1/r
# mount /dev/vg1/

regards.

[Joseph Loo]

hi,

forgot something before vgextend:

# pvcreate -f /dev/rdsk/c10t6d6
# pvcreate -f /dev/rdsk/c10t6d7

regards.

[Sudhaadm]

How can i give the extent size.
this disk is EMC disk.And need clear steps because i am new to HP-UNIX

[Sudhaadm]

I need to add 10Gb space on each FS or logical volume.

[Joseph Loo]

hi,

could u reply on this:

# vgdisplay -v vg1

from the output, what is the file system u like to increase.

regards.

[Sudhaadm]

I need to add space 10 gb on each of these /data 06, 04,05,02,07

vg03_chardata is having lv 's /data02/04/05/06
/dev/vg04_chardata is having lv /data07

[Sudhaadm]

Hi Josep/Sivakumar,

Thanks for the reply and help us to do the step by step as it is critical server for us.

[Joseph Loo]

hi,

u have 2 disks, each 36GB and u like to place the disks in 2 separate volume groups, vg03_chardata and vg04_chardata. u can only add either both disks to either volume group or one disk to each volume group.

so, if u like to add 10GB to each filesystem, i.e. 40GB for vg03_chardata and 10GB for vg04_chardata. one disk must be added to each volume group.

also, since the disk is only 36GB, u may have to resize how many to allocate for each file system in vg03_chardata.

please reply on bdf and also exact size if u like to have the commands to apply.

another method is to do it from sam if u r unfamiliar with the commands.

r u also on OnlineJFS:

# swlist -l product|grep -i jfs

regards.

[Sudhaadm]

Hi thanks for the reply.
Any how please provide the steps and can try to to request to add one more disk for that VG.

hi,

ok. follow this steps:

# pvcreate -f /dev/rdsk/c10t6d6
# pvcreate -f /dev/rdsk/c10t6d7

1 36GB disk to each volume group, unless u can add another disk.
# vgextend /dev/vg03_chardata /dev/dsk/c10t6d6
# vgextend /dev/vg04_chardata /dev/dsk/c10t6d7


as i have stated in your case, u can only have 1 disk allocated to each volume group, so given a 36GB, i have added 8GB to these 4 logical volumes in /dev/vg03_chardata:

# lvextend -l 13936 /dev/vg03_chardata/lv_data02
# fsadm -F vxfs -b 114163712 /data/data02

# lvextend -l 13936 /dev/vg03_chardata/lv_data04
# fsadm -F vxfs -b 114163712 /data/data04

# lvextend -l 9632 /dev/vg03_chardata/lv_data05
# fsadm -F vxfs -b 78905344 /data/data05

# lvextend -l 9624 /dev/vg03_chardata/lv_data06
# fsadm -F vxfs -b 78839808 /data/data06

added 10GB to this logical volume:
# lvextend -l 14192 /dev/vg04_chardata/lv_data07
# fsadm -F vxfs -b 116260864 /data/data07


to verify:
# vgdisplay -v /dev/vg03_chardata
# vgdisplay -v /dev/vg04_chardata

hi,

for /dev/vg03_chardata, u cannot exceed the max physical volume which is 6 (in your case). default max_pv is 16 per volume group, someone must have change it when doing a vgcreate.

this is not going to be easy cause u have to re-create the entire volume group:

http://www1.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000063200398


for /dev/vg04_chardata, the max physical volume which is 16, thus u may go ahead with it.

regards.

[Devender Khatana]

Hi,

Max_PV parameter was not defined properly when your vg03_chardata vg was created. It can only support 6 physical devices and it has allready got 6. This parameter can not be changed and you need to recreate atleast this VG from the scratch.

Backup files under all file systems in vg02_chardata VG, remove and recreate VG and restore backup.

The extending part can be accomplished with other VG allthough without problems.

Also you want to add 10GB in four file systems in vg03_chardata volume group. This require 4*10=40GB free space but the lun you are adding is of 34 GB only.

While resturcturing also take a note of this.

HTH,
Devender

Hi Joseph i had done big mistake and added both disks in same VG...how can ireuce online...

Please sorry for the trouble.

[Sudhaadm]

Hi Joseph/all

Is it possible to reduce harddisk from /dev/vg04_chardata.
Mistakely i added 2 hard disks on same vg.I supposed to add only one hard disk..
Urgency...

[Joseph Loo]

hi,

have u done lvextend for the logical volume /dev/vg04_chardata/lv_data07? if u have not:

# vgreduce /dev/vg04_chardata /dev/dsk/c10t6d6

and reply:

# strings /etc/lvmtab

to verify

regards.

[Sudhaadm]

Ohhh gr8 joseph..thanks alot

i reduced successfully..i did 't added this disks to lv..and what about that previous error.Devendra suggested that we can add one more disk on /dev/vg03_chardata.

hi,

i found a doc which u may reference to:
