With that config I would have expected the Sandbox to take longer. :-)

Paul,

All ASPs will say "unprotected" unless protected by mirror, See that the Unprotected applies to the ASP itself but each drive is protected.

Best Regards,

1) On the " Display disk configuration status" why does the ASP

2) Is there a green screen equivalent cmd to Ops Navigator New Disk

Actually you cannot do RAID on those at the guest level as there is no
'RAID' card available there.

You CAN do Mirror as that is done by IBM i. It's not recommended
though although I'll happily let you do it because I sell Disk. :-)
:-)

The only reason I can really think for doing this is if you have TWO
host partitions and you mirror all the disk on the guest partition to
both hosts. Since the disk will be RAID protected at a minimum at the
host level you're consuming a LOT of disk this way but you ARE
allowing for a failure of one host partition not to take you down.

Larry,

Since you mentioned virtual disks, should virtual disk also have
disk
protection, such as RAID-5?
If so, then these would be protected twice, once on the host and
also on
the quest.

I have a 2 small guest LPARs, only one virtual disk. In this
situation,
not enough disks for a parity set.

Aha! Somehow I had the idea that these were virtual disks to a
hosted
partition. That not being the case you are of course correct!

My intention here, (not previously stated) was to remove disks from
the
ASP, without stopping parity, using the existing parity set.
To delete disks, I would have had to stop parity, which requires an
IPL
to DST.
After parity was deleted, disks could have been deleted.

Could have skipped these two steps and saved some time. Step 3
below does all of that and is a bit more efficient at it. It's much
more efficient if you IPL to DST but as you stated you didn't want to
do that you're good.

3) STRSST, 3. Work with disk units , 2. Work with disk
configuration , 12. Work with removing units from configuration ; 3.

Had you deleted those disk units from your host and the

spent the time creating them on your host partition so pretty likely a wash there.

5) Tested a RSTLIB, forcing the RSTASP to ASP 2, worked with no issue.

ASPs are valid. Recovery .
. . : Use the Work with ASP Descriptions using
BRM (WRKASPBRM) command

determine whether the ASP description exists and
verify the parameter

Clearly a BRMS error. With system ASPs (2-32) only a number is
valid
and with iASPS (33 & up) only a name is valid. So BRMS seems in error
requiring a name for something that does not have one. ASPs 2-32 also
do not have an ASP Device.

7) WRKASPBRM revealed two ASPS. By default, *NONE is auto created
as
the name for ASP 2. BRMS did not like this.

*SYSTEM 00001 *SYSBAS *NONE *YES
*NONE 00002 *SYSBAS *NONE *YES

8) 2=Change the ASP name from *NONE to SLICES (this can be
anything, not actually referenced on the RSTLIBBRM command) Currently
checking with BRMS group for the restore rules on ASP Name)

*SYSTEM 00001 *SYSBAS *NONE *YES
SLICES 00002 *SYSBAS *NONE *YES

9) Reran RSTLIBBRM command, successful restore of the entire
library
to ASP2.
10) Need to finish restoring 30 remaining app libraries to ASP2.
11) Then let the testing begin.

Overall well done!

I need to create ASP2 for testing SSD/HDD mixture.
What would be the easiest way to do this using current existing disks.
Can a client LPAR have 2 ASPS.


Thank You
