SAN Migration

Hi,

In my environment we had planned to migrate from old HDS9960 to new HDS9990. Storage team will be doing a copy (cloning) from old to new for Open 9. We have some Open 3 also which we need to manually migrate. Could anyone let me know the procedure for the same for this migration on Unix part.

Re: SAN Migration

We did one just a while back in just a few days. HP offers some pretty neat tools to do it, but I opted for just hooking up the new storage system at the same time as the old, and then creating the new mount points. Afterwards, we shutdown down all database areas, and copied to the new. Renamed the new mount points to look just like the old, and we were able to start up the databases - no problem.

This isn't complicated - you MIGHT want to use HP's or Hitachi's tools if you can't get some down time. HP consulting can handle this for you quite easily, they are very competent and do work like this very well.

Re: SAN Migration

If you have room in your volume group - then mirroring works great - and no outage required.

Second option - copy with vxdump.

This is how I did it:

vxdump -0 -f - -s 1000000 -b 16 /oracle | (cd /new/oracle ; vxrestore rf -)

Then - once done - unmount them all - modify your /etc/fstab file to mount the new SAN at /oracle

HI

we had somehow same type of migration last year. We used Mirror-UX to migrate the data.
You can do it as long as you keep same emulation.

Re: SAN Migration


And can anyone tell me, once the cloning part on HDS completes to new HDS what i need to do on HP UX box ? Device files would have been changed ?

Re: SAN Migration

All you should need to do is run an ioscan -fnC disk, then insf -e

Then add the devices to your vg's.
