Hello Experts,

HI Sharif,

To expand oracle filesystem, you need to add this LUN to the volume group containing the filesystem.

Do a

bdf /oracle (say /oracle is the filesystem you are trying to expand)

Note the logical volume in the first column. The first two fields in the logical volume gives you the volume group. If /dev/vg01/oracle is the logical volume, then /dev/vg01 is the volume group.

Find out the disk (LUN) corresponding to the hardware path from ioscan

#ioscan -f
#insf
#ioscan -fnC disk

(say the disk is /dev/dsk/c1t0d1). Follow this procedure to expand your volume group.

#pvcreate /dev/rdsk/c1t0d1
#vgextend vg01 /dev/dsk/c1t0d1

Now you have enough space in vg01 to expand oracle filesystem. Then stop the application and unmount /oracle filesystem.

#umount /oracle
#lvextend -L new_size_in_mb /dev/vg01/oracle
#extendfs /dev/vg01/roracle
#mount /dev/vg01/oracle /oracle
#bdf /oracle (verify the size)

If you have Online JFS, then you don't have to stop the application and unmount oracle. Follow these steps if you have OnlineJFS.

#lvextend -L new_size_in_mb /dev/vg01/oracle
#fsadm -b new_size_in_blocks /oracle

new_size_in_mb = Total size you need
new_size_in_blocks = new_size_in_mb * 1024

#bdf /oracle (verify the size)

Only problem here is if your new LUN is bigger than the existing LUNs in your volume group vg01, then the entire size will not be used unless the vg01 was created with non-default maxPE value.

Thanks alot Sridhar,

since i did not work on EVA before

2> kmadmin -L swspData
3> config -M swspData -u

Thanks,
