What will be the procedure to can recover these filesystem ?

# mount -a
vxfs mount: /dev/vg02/lvol1 is already mounted, /oracle is busy,
or allowable number of mount points exceeded
mount: /dev/vg00/lvol8 is already mounted on /var
mount: /dev/vg00/lvol7 is already mounted on /usr
mount: /dev/vg01/lvol2 is already mounted on /usr/sap
mount: /dev/vg00/lvol6 is already mounted on /opt
mount: /dev/vg00/lvol5 is already mounted on /home
mount: /dev/vg00/lvol4 is already mounted on /tmp
mount: /dev/vg00/lvol1 is already mounted on /stand

Don't have a backup? Bad luck.
You should learn the lesson and backup your systems.

Dear Experts,


Iam getting the following error

vxfs mount: /dev/vg02/lvol1 is corrupted. needs checking

When i put mount commmand
# mount -F vxfs /dev/vg02/lvol1 /oracle
vxfs mount: /dev/vg02/lvol1 is corrupted. needs checking

Please have a look into it..

Check it

# fsck -F vxfs /dev/vg02/rlvol1

and follow the document I posted earlier.

Dear Expert,

# fsck -F vxfs /dev/vg02/lvol1
vxfs fsck: file system had I/O error(s) on meta-data.
vxfs fsck: file system had I/O error(s) on user data.
vxfs fsck: fsck read failure bno = 13092100, off = 0, len = 8192
full file system check required, exiting ...

This is the output i got..

Do the "dd" check (see manual above).

Hi Naveen:

Try a full check (as the last error suggested):

# fsck -F vxfs -o full /dev/vg02/rlvol1

However, as Torsten has suggested, look at "When Good Disks Go Bad" guide. You are probably going to need to replace the damaged disk and unless it's mirrored, restore the missing data from a backup.

Regards!

Dear Expert,

# fsck -F vxfs -o full /dev/vg02/lvol1
vxfs fsck: file system had I/O error(s) on meta-data.
vxfs fsck: file system had I/O error(s) on user data.
vxfs fsck: fsck read failure bno = 13092100, off = 0, len = 819
full file system check required, exiting ...

I read that document and checking everything it says ok and good,but i cant understand where it goes wrong.

Did you perform the "dd"? How? Results?

# dd if=/dev/rdsk/c5t0d3 of=/dev/null bs=1024k count=64&
