Re: Adding additional storage to ASP

A little more info.  The current storage size is 2,997.5 GB.  Capacity on the existing disks is 124.9 GB each, additional disks are 136.3 GB each (reported from iSeries Navigator).

I used the AS/400 term loosely.  It's a Power 720 system.  I currently have 24 126.9 GB drives protected with raid 5 and am needing add an additional 24 139 GB drives with the other drawer I mentioned earlier.

Thanks for the response!

As to the breaking of the ASP that's unlikely but there are some things
that you are clearly aware of with your comments. However:

You didn't say how big the current disks are or the quantity of them.
You also didn't say how big the new disks are or how many of them are
being added to the system ASP.
We also don't know the total capacity of your current storage, how full
it is, or if it's RAID or Mirror protected or (shudder) not protected at
all!

Without that the best advice is to assure the new disk units are
protected when adding them to the ASP and be CERTAIN to use the "ADD AND
BALANCE" option when you do that. Failure to select "AND BALANCE" has
been known to bring systems completely to their knees. This is in
extreme situations but avoiding such problems is your best defense.

Better advice is possible with additional information.

I recently added an additional disk storage unit to my AS/400.  It's IBM Feature Code 5887, IBM EXP24S SFF Gen2 I/O Drawer.  These disks are supposed to be added to the system and I'm a little unsure about how to do this.

I'm worried that I'll break the system if I add the additional 24 disks to the System ASP.  The new disks are a larger size than the existing ones.  I'm looking for a little insight about getting these disks added and usable by the system.

Thanks in advance,

BJ
