How to Increase size in sapdata4 .....

[Former Member]

Hi Experts,

I have removed 18 GB from Logical Volume vol13 (#/dev/vg01/lvol13 /sapcd) in fstab. Now I want to allocate this space in /oracle/DEV/sapdata4.

How to add this free 18 GB in sapdata4 ? The Logical Volume which I have removed also resides in same logical volume vg01.

Pl. guide me. We are using HP-UX operating system.

increase your logical volume/file system...for example by using SAM...

-> which hp-ux release do you use?

-> which filesystem type do you use?

Unix Version : HP-UX 11i

File System : File System vxfs

-> extend logical volume to the desired size (check volume group!) using <b>lvextend</b>; for example:

> <i>lvextend -L yyyy /dev/vgxx/lvolxx</i> (with yyyy = desired size)

-> extend file system to the desired size using <b>fsadm</b>; for example:

> <i>fsadm -F vxfs -b xxxx /fsdir</i> (with xxxx desired size in KB)

full syntax of both commands can be found through <b>man</b> on unix level...

Hi Andreas,

Before doing these steps Shall I unmount sapdata4 from that logical volume?

If you have OnlineJFS you don't need to umount sapdata4. Use "swlist -l bundle | grep JFS" to check if it is installed, otherwise you have to umount sapdata4 and use extendfs command.

Did you just remov the fstab entry? You need umount /sapcd and remove /dev/vg01/lvol13 using lvremove. Also does the lv /oracle/DEV/sapdata4 mounted on belong to vg01? If it belongs to different vg you cannot extend.
