Re: WRKDSKSTS and finding true disk space usage

Hi Matt

I re-worked my maths on this; I thnk you have 12 x 140GB drives including a
hot spare

10 X 140 / 11 = 127 (this is how I could calculate the size of an
individual drive with RAID 5 over 11 drives)

10 X 140 is more or less 1395, so this seems accurate

Hi Matt

What does WRKDSKSTS show ? How many drives (count them)

Are you sure you have both RAID and a Hot Spare ?

A guess indicates to me this is 12 X 140GB drives running RAID 5

Says Active under protection status.

I think I see how wrksyssts is getting 1395. That is 11 x 127.

The problem is, that is not really how much space is available as those
11 drives are in a RAID 5, so it should be about 1270 GB.

WRKSYSSTS doesn't seem to have knowledge of raid configurations and
adjust accordingly?

*WARNING**

The hotspare should NOT BE LISTED in WRKDSKSTS. If it's showing there and
has an ASP number next to it you are UNPROTECTED!!

Hit F11 to see protection. If there is nothing under 'Protection" then
you need to remove this disk from the ASP IMMEDIATELY! Your hot spare is
set incorrectly as an available disk not a Hot Spare in this case!!

Does anyone know why WRKDSKSTS shows total ASP size as 1395GB when it

should really be around 1268?

We have 11 x 127GB drives in RAID 5 which should equal about 1268. We

also have one hot spare, bringing it to 1395.

Why would WRKDSKSTS show the hotspare as usable drive space??

Additionally, the percentage ASP used is off as well because of this.

Lastly, does the system incorrectly calculate total used disk space

because of the recursive sym link in QOpenSYs that links back upon itself
up to a depth of 10 times (therefore inflating QOpenSys consumed space by
10x)?

Thanks!
