Extend Raid
Dirk Emmermacher
For several years we use a HP ProLiant ML350 G3 machine with NW6.5.7. Now
its time to extend the Raidsystem. What's here the best method? Using the
HP-Cdroms or the CPQONLIN.NLM. For the moment the server has four disks as
RAID5 (3 + 1 Hotspare).
We want add two additional disks.
What is say about the risk to lose any data on the server?
We never extend a Raid before, so I don't have any experiences here.
Thanks in advance for your opinions.
Best regards.

This is what I always do:
1. Make sure I have backups
2. Add the disks, one at a time
3. Use CPQONLIN to assign to array
4. Let the controller stripe out the data
5. Use CPQONLIN to create a new "disk" on the new free space
6. Use NSSMU to create a new volume or assign new space to exiting.
I have never had a RAID failure extending this way on HP/Compaq.

Thanks four your answer.
That's the information I expected to hear.
So I wait for a disaster recovery option for my backup program and tahn we
wil start with the new disks.
