Extending Filesystem

[kunjuttan]

Hi Gurus,
I am having an Hp rx7640 server running hp-ux11.23 os.Now I just want to confirm the steps to extend the filesystem.Please help.i am giving the steps below.pls tell me if there is any error.
Existing Fs size is 50GB.I want to make it 100GB.SO what will be the size I have to give with lvextend command??

Create PV,
#ioscan -fnC disk
#pvcreate /dev/rdsk/cxtxdx

Extend the existing VG,
#vgextend vgsapdata1 /dev/dsk/cxtxdx

Extend the LV,
#lvextend -L xxxM /dev/vgsapdata1/lvsapdata1

Unmount the FS,
#umount /db2/PBI/sapdata1

Extending the FS,
#extendfs -F vxfs /dev/vgsapdata1/rlvsapdata1

Mount the extended FS,
#mount /db2/PBI/sapdata1

hi,

lvextend -L 102400 /dev/vgsapdata1/lvsapdata1

1GB = 1024 MB so if you like to have a 100 GB you need to multiply this value.

Hi Mashe !

In your lvextend command , give the value for xxxM in MB equal to 100 GB

If you have online JFS then you can extend the filesystem without unmounting.

#swlist -v|grep -i "OnlineJFS"

Hi,

If you have MirrorDisk/UX then you can extend the filesystem with mirror option.

# lvextend -m 1 /dev/vgsapdata1/lvsapdata1
