I have a rx2620 server with only 1 x 73GB root internal HDD and I need to add on the following parts on it.
I need to ****
1) Replace the only internal 73GB root HDD with 300GB HDD. Then restore all to the 300GB HDD. Add on second 300GB HDD
2) Both 300GB HDDs are mirror ( Raid 1 )
May I know that do I do it correcly with the following steps ?
1. Install the new DAT160 tape drive & Smart Array 6402.
2. Perform a make_recovery back up.
3. shutdown the system and replace the 73GB HDD with 300GB HDD and add second 300GB HDD. 4. Power on the system and perform RAID 1 configuration.
5. restore from make_recovery tape.

Well you can do this, if you wish to spend the money on ythe new controller, but there is another way of doing this, assuming you have MirrorDisk sogftware.
With an rx2620 server, you are running either HP-UX 11iv2 or 11iv3. Why not use DRD to accomplish this? Insert the new 300GB disc while still using the current disk. Use drd clone to clone the exisiting disc to the new one Activate the clone and test it boots ok If it does, remove the origional small disc, insert the second 300GB disc, an dthen perform the standard mirroring steps for an Integrity server.
If you want to do this, you need to combine both procedures to bring the smartarray into play.
Since the array disks should be in the lower 2 slots, you first need to place the current boot disk in the upper slot and adjust your system to accept this.
Now you can install and configure the smartarray, then continue with DRD.
Another simple way is to use vgmodify (in case you have Mirror/UX). 1. Add 1 300GB disk (pvcreate -b) 2. vgextend vg00 <new disk> 3. mirror all lvols 4. vgreduce vg00 <old_73gb_disk> 5. replace 73GB disk with second 300GB disk 6. vgextend vg00 <second_disk> 7. again mirror all lvols
Follow the known procedure for mirroring boot disks. Now boot once into maintenance boot with "vmunix -lm" and change max_pe with vgmodify. It may be necessary to free up the first extent of the disk. This might be a little tricky with 11.23, but works fine with extended pvmove features in 11.31. vgmodify has a preview feature, so you can try out what will be done before actually doing it... In the end, check, that all boot volumes are still configured (with lvlnboot) and eventually restore the boot lv. Prepare the possibility to boot from DVD or remote lan, in case something goes wrong here. If you mess up thing completely, you can continue to restore your Ignite-Backup to the new disks.
This is the method with the least necessary downtime, but you need to know what you're doing...
