Re: Reallocate storage

Moving disks will be involved UNLESS, as another poster suggested, you are
guesting lpars.

Want to see? do a WRKHDWRSC *STG You may see something like the
following:
Resource Type-model Status Text
CMB02 268C-001 Operational Storage Controller
DC02 6B02-001 Operational Storage Controller
CMB04 576B-001 Operational Storage Controller
DC04 576B-001 Operational Storage Controller
TAPMLB02 3576-05B Operational Tape Library
TAPMLB04 3576-05B Operational Tape Library
CMB13 575C-001 Operational Storage Controller
DC03 575C-001 Operational Storage Controller
CMB14 575C-001 Operational Storage Controller
DC06 575C-001 Operational Storage Controller
CMB15 575C-001 Operational Storage Controller
DC09 575C-001 Operational Storage Controller
CMB16 572F-001 Operational Storage Controller
DC10 572F-001 Operational Storage Controller
...
Yours will differ. If I go all the way down to DC10 and use 9=Work with
resource I can see that it has 4 disk drives.
Resource Type-model Status Text
DC10 572F-001 Operational Storage Controller
DD081 58B0-109 Operational Disk Unit
DD082 58B0-109 Operational Disk Unit
DD083 58B0-109 Operational Disk Unit
DD084 58B0-109 Operational Disk Unit
D05 509A-001 Operational Device Services
D04 509A-001 Operational Device Services
If I go back up to the CMB16 just above it I see they are controlled by
this card 572F-001, in this slot U789D.001.DQDZZHD-P1-C4.
On your other lpar you will see those disk drives are controlled by a
different card in a different slot.

UNLESS!! you are guesting.

I have a "host" lpar called MAIL3. It has two guests: GDI, GDWEB3. On
MAIL3 if I do a WRKNWSSTG I will see:
Name Text Size
GDISTG01 GDI lpar 250003
GDISTG02 GDI lpar 100006
GDWEB301 GDWEB3 - INTERNOTES3 300002
I created two "disks" for GDI and one for GDWEB3. MAIL3 has 12 arms, now
shared by all three lpars. I do not have to have a separate disk
controller card and raid card for each lpar.
On GDI if I do a WRKHDWRSC *STG there's two disk drives and two optical
drives.
Resource Type-mode
DC01 290A-001
DD001 6B22-050
DD002 6B22-050
OPT01 632C-002
OPT02 632C-002
WRKDSKSTS on GDI will show
Size %
Unit Type (M) Used
1 6B22 233020 36.9
2 6B22 93212 40.8

In theory I could delete objects on GDI to free space. Do a STRASPBAL
*ENDALC on unit 2, some other mumbo jumbo to free it up and delete it.
Giving me back some space on MAIL3. I would get the space back as soon as
I safely deconfigured it from GDWEB3 and did a DLTNWSSTG on MAIL3.

Guesting can save you some serious cash.

Think of the consultant who could go to a customer and simply do a RST to
get one item from /QFPNWSSTG restored, do some steps on the HMC and a
couple of commands on their existing i, and have a fully functional lpar
cranking without all of those pesky steps from the GO RESTORE menu.
