Re: Need to create ASP2 to for testing SSD/HDD mixture

Larry,

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

Display Disk Configuration Status

Serial Resource
Hot Spare
ASP Unit Number Type Model Name Status
Protection
1
Unprotected
1 Y010EA00CE3D 19B3 099 DMP048 RAID 5/Active N
2 Y010EA00CE3G 19B3 099 DMP002 RAID 5/Active N

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

Paul

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.

Here are the processes I used to create and test ASP2, using existing

This was a sandbox LPAR, 8205, .3 CPU, 8gb mem, CEC controller, 8

1) STRASPBAL TYPE(*ENDALC) UNIT(6 7 8)
2) STRASPBAL TYPE(*MOVDTA) TIMLMT(*NOMAX) PRIORITY(*MEDIUM) - This

took a while 10-20 hours.

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.
Remove units from configuration ; 4=Remove unit from configuration

4) Using Ops Navigator New Disk Pool Wizard , Configuration and

Pools ; New Disk Pool, Created ASP2, (Unchecked Protect data in this
pool because disk already protected via Raid5) Add New Disk, (added
6,7,8 to ASP 2. This also took a while 10-20 hours)

Had you deleted those disk units from your host and the re-created

them the ADD would have taken just seconds. Of course you would have 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.

Cause . . . . . : BRMS does

not recognize 00002 as a valid ASP name or

number. Either the ASP

description is not defined or an auxiliary storage

pool device is being

specified when only system (1) or basic user (2-32)

ASPs are valid. Recovery .

. . : Use the Work with ASP Descriptions using

BRM (WRKASPBRM) command to

determine whether the ASP description exists and

verify the parameter

supports use of auxiliary storage pool devices.

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.

ASP ASP ASP ASP Hierarchy

Migration

Name Number Type Class Priority Eligible

*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
