Add drive to existing Array
I have an hsg80 controller and would like to add 1 drive to an existing array via the command line interface.
Can anyone tell me the commands for this, or point me to some documentation that explains the procedure?
Thank you.

Re: Add drive to existing Array
First you need to figure out where you will insert it, slide the drive in HALF WAY, press the Quiesce button for the shelf on the controller, wait for the normal blinking (drive activity) to pause (takes several seconds -- 10?), slide the drive in and lock it down, and wait for the shelf to resume. Give it a minute.
Then there is a program that is run at the command line. I think it is CONFIG, as in "RUN CONFIG". This scans every shelf on the controller and generates an ADD DISK command for each disk that is physically present but not in the software list. At that point, you are ready to do something with the drive.
Check that Reference Guide to make sure the program *is* CONFIG. You can also "DIR" to see what programs *are* available within the controller.

Re: Add drive to existing Array
it is not possible to expand an existing storage set by adding a disk drive to it!
You need to:
- back up all your data
- DELETE the Unit
- DELETE the StorageSet
- sometimes INITIALIZE every disk drive to get rid of meta-data
- create a new, larger StorageSet with the ADD command
- INITIALIZE the new StorageSet
- ADD a new Unit, best with the DISABLE_ACCESS_PATH=ALL switch
- grant access to the servers with
-- set Unit ENABLE_ACCESS_PATH=(connection1, c2,...)
- make the Unit available to the operating system
- restore the data

Re: Add drive to existing Array
That sounds very odd, it's only 4 year old. It's been about 10 years since I seen a controller that couldn't expand an existing array. Isn't that the whole point in having a SAN?

Re: Add drive to existing Array
A SAN is just a transport media for SCSI commands - it has nothing to do with the RAID implementation.

Re: Add drive to existing Array
It'll be hard to convince my client this isn't possible for something that is fairly new. Is there documentation for this that I can point them to?

Re: Add drive to existing Array
It is also possible that at the time of purchase, the company did not think it would ever have to expand in this way.
I've seen it all too many times.
The simple fact remains that the only way is how it was stated...
or if you have enough Hard Drives and available slots, you can by-pass the backup/restore. Put in new drives, create the unit, present to the host, format and copy the data over. Then you can re-utilize the old drives for something else.
Hmmm, 4 years, perhaps they can get a good deal on a trade in/trade up.
As for docs, the command reference might be ok. The fact that there is no option to "add" a disk to an existing diskset or to "expand" a diskset is proff that it can't be done. (Expanded that is). That, and the backing of all the Storage Engineers here in the ITRC/Business forums, mayb be enough.
