Re: Disk reconfiguration for upgrade

I agree with Chris... the 17s are fine even for V5R4. 

While I haven't tested this on a system for quite sometime... The AS/400s 
could find a loadsource and IPL from almost anywhere the system. With the 
i5s they are pretty insistent that the loadsouce goes into P3. With that 
said, I've always put the loadsource in its proper position as not to 
confuse me or someone else after me trying to fix/upgrade the system.

Like Chris I would use the STRASPBAL *ENDALC cmd to tell the system not to 
put any new data on drive you select to remove. Then use the STRASPBAL 
*MOVDTA to have the system concurrently migrate as much data of the 
selected drives as possible. NOTE: This can cause a  hit on performance, 
so don't do this when the system is really busy.

Disk reconfiguration for upgrade







Any advice please

We are looking to upgrade OS on our 270 (currently V5R2)

We believe we need a larger disk for our load source in order to do this, 
and are looking at moving to 17.5gb or 35gb disk drives.

Our current disk config is as follows :

Parity Set 1
4 * 6.4gb 6717

Parity Set 2
8 * 7.5gb 6717 (including load source)

Physically we  have 2 * 6 slot units. Both currently full.
The first unit contains 4 drives from Parity Set 2 (including the load 
source) and 2 from Parity set 1
The second unit contains 4 drives from Parity Set 2 and 2 from Parity set 
1

Current disk usage is 57%

Is it possible, by some combination of removing existing drives, switching 

off parity, adding the new larger drives, to move load source to the 
larger disks whilst avoiding full restore ?
