1st drive: hold Oracle installed software and one swap device;
2nd drive: hold only Oracle datafiles.
They are 8G drive to be replaced by 36G, no mirror.
All comments are appreciated!
Solved! Go to Solution.

SolutionYou really need a better plan B; more drives or maybe a used array because anything will be better than the proposed solution. You can pick up used drive arrays for almost nothing these days.

Re: Choice of Replacingn Oracle Hard Drive
So I either replace the one with swap and software or the one with datafiles.
I need comments (as tear down swap is not funny).
Thanks.

I would backup to tape (or spare disk if you have it); yank both 8GB drives and throw the 36GB drives in. You then create your VG's, LVOL's, and filesystems. Mount the filesystems and restore from backup.

Re: Choice of Replacingn Oracle Hard Drive
if the new disk is faster than the previous one, i would prefer to use it for the Oracle Datafiles. Of course, it depends on the level of tests you have opted for.
good luck.

Re: Choice of Replacingn Oracle Hard Drive
I would suggest take complete data backup first to be safe. Then connect new disks and create new VG & file systems on them. Now mount them onto new paths & copy data with oracle shutdown to the new mount point. Remove swap and recreate on the VG in new disks.
Once copy is complete mount new disks on the same path where earlier disks were mounted.
Suppose old 8G disks are mounted at :-
/oracle
/data
& swap
Then mount new disks at /oracle1 & /data1
With oracle shut perform copy using cpio command.
#find /oracle -name "*" -print|cpio -pdmv /oracle1
Repeat same for /data
Recreate swap on new disks after removing swap entry from /etc/fstab & reboot.
Now mount /oracle1 to /oracle & /data1 to /data.
This shall be very fast as you will not require to restore from backup which takes long time but can not be done online unless you have option for mirroring.
HTH,
Devender
