Jean,

If you have 6 disks in a 620 then you have disk can space for 10 drives. You can add drives to the exiting RAID set. So for the price of 4G drives today I'd just purchase 4 of those boys used and stuff them in there. Add them to RAID then add them to the ASP and shazaam you get 16 GB more space. Hands down the cheapest fastest and least exposure.

Hi all,

We have a 620 in V4R2 with 6 disks (4.19 Gb #6807), 1 RAID-5 controller (#2741) 
and 1 tape unit (1/4 inch 2.5 Gb #6481). It will die at end 2005. So we don't 
want to make too much investments, but we have to add some disk storage. We 
will ask IBM if we can add new cards. But we thought about replacing some cards 
by others with higher volume (perhaps 8.58 Gb). At that level, is it possible 
to disable a 4.19 Gb disk, unmount it, mount a new 8.58 Gb one, activate it 
under READ-5 and repeat the operation for a second one ? Or is it easier to 
backup the whole machine, stop it, replace some disks and restart from tapes ?

Thanks.
