Using Shared Storage Pools on VIOS
So here is a quick one line script “ncluster”
ncluster ()
{
/usr/ios/cli/ioscli cluster -status -verbose -fmt : -field "Node State" "Node Repos State" "Pool State" "Node Roles" "Node Upgrade Status" "Node Name" | \
awk -F: 'BEGIN { printf "No State Repos Pool Role ---Upgrade-Status--- Node-Name\n" ; } { printf "%2d %5s %5s %4s %4s %20s %s\n", NR, $1, $2, $3, $4, $5, $6; }'
}
And “nlu” to list shared pools
nlu ()
{
if [[ $(whoami) != "root" ]]
then
command=$(whence $0)
# echo DEBUG I am padmin so restart $command again as the root user
echo "$command" $1 | oem_setup_env
else
# echo DEBUG now I am root
# lowercase the parameter with tr to avoid input case errors
case `echo $1 | tr "[A-Z]" "[a-z]" ` in
1 | -sizemb) COLUMN="-nk 1" ;;
2 | -usedmb) COLUMN="-nk 2" ;;
3 | -used | -used%) COLUMN="-nk 3" ;;

echo $0 "Nigel's lu command with improved layout and column ordering"
echo $0 "[-sizemb | -usedmb | -used | -type | -tier | -name (default)]"
exit 0
;;
*) COLUMN="-k 6" ;;
esac
echo " SizeMB UsedMB Used% Type Tier Name"
/usr/ios/cli/ioscli \
lu -list -field LU_SIZE LU_USED_SPACE LU_USED_PERCENT \
LU_PROVISION_TYPE TIER_NAME LU_NAME -fmt : \
| awk -F: '{ printf "%7d %7d %4d%% %5s %5s %s\n", $1,$2,$3,$4,$5,$6}' \
| sort $COLUMN
fi
exit 0
}
And below the sample output
$ ncluster No State Repos Pool Role ---Upgrade-Status--- Node-Name 1 OK OK OK 2.2.4.10 UP_LEVEL indigovios1.aixncc.uk.ibm.com 2 OK OK OK 2.2.4.10 UP_LEVEL rubyvios1.aixncc.uk.ibm.com 3 OK OK OK 2.2.4.10 UP_LEVEL emeraldvios1.aixncc.uk.ibm.com 4 OK OK OK 2.2.4.10 UP_LEVEL emeraldvios2.aixncc.uk.ibm.com 5 OK OK OK 2.2.4.10 UP_LEVEL rubyvios2.aixncc.uk.ibm.com 6 OK OK OK 2.2.3.52 ON_LEVEL purplevio1.aixncc.uk.ibm.com 7 OK OK OK 2.2.4.10 UP_LEVEL purplevio2.aixncc.uk.ibm.com 8 OK OK OK 2.2.4.10 UP_LEVEL limevios1.aixncc.uk.ibm.com 9 OK OK OK 2.2.4.10 UP_LEVEL limevios2.aixncc.uk.ibm.com 10 OK OK OK 2.2.4.10 UP_LEVEL greenvios1.aixncc.uk.ibm.com 11 OK OK OK DBN 2.2.4.10 UP_LEVEL greenvios2.aixncc.uk.ibm.com
DBN is the “database node” I think means it is the node that updates the repository.
Not the script does not colour the output RED - but that would be cool!!
Here is another example after the SSP5 has noticed all the VIOS are at the higher level
No State Repos Pool Role —Upgrade-Status— Node-Name 1 OK OK OK 2.2.4.10 ON_LEVEL bronzevios1.aixncc.uk.ibm.com 2 OK OK OK 2.2.4.10 ON_LEVEL silvervios1.aixncc.uk.ibm.com 3 OK OK OK 2.2.4.10 ON_LEVEL goldvios1.aixncc.uk.ibm.com 4 OK OK OK 2.2.4.10 ON_LEVEL orangevios1.aixncc.uk.ibm.com 5 OK OK OK DBN 2.2.4.10 ON_LEVEL redvios1.aixncc.uk.ibm.com $
The default format that zooms off the screen is below
$ cluster -status -verbose Cluster Name: globular Cluster Id: 9230352855ff11e3ba5b0e0a51517820 Cluster State: OK Repository Mode: EVENT Number of Nodes: 11 Nodes OK: 11 Nodes DOWN: 0 Pool Name: Pacific Pool Id: 0000000009893E510000000052939733 Pool Mirror State: SYNCED Node Name: indigovios1.aixncc.uk.ibm.com Node Id: bf999ca460fb11e492d200006cae8b6a Node MTM: 8231-E1C020659FDR Node Partition Num: 1 Node State: OK Node Repos State: OK Node Upgrade Status: 2.2.4.10 ON_LEVEL Node Roles: Pool Name: Pacific Pool Id: 0000000009893E510000000052939733 Pool State: OK Node Name: rubyvios1.aixncc.uk.ibm.com Node Id: 796dc49ef4ad11e4b72000006cae8b6a Node MTM: 8408-E8E0221D494V Node Partition Num: 1 Node State: OK Node Repos State: OK Node Upgrade Status: 2.2.4.10 ON_LEVEL Node Roles: Pool Name: Pacific Pool Id: 0000000009893E510000000052939733 Pool State: OK
Fortunately, the SSP designers are very clever. The lu options allow you a raw format. As an example:
$ lu -list -field LU_SIZE LU_NAME -fmt : 32768:testa 40960:testb 38912:vm97boot 8256:vm97data 8192:testc 8192:v23456789012345678901234567890 38912:vm96boot 8256:vm96data
OK, not pretty but nothing awk can’t sort out.
As we no longer need a sort the LUs by name we can reduce the ksh script to just one line (4 for readability):
echo “SizeMB UsedMB Used% Type Tier Name” /usr/ios/cli/ioscli lu -list -fmt : \ -field LU_SIZE LU_USED_SPACE LU_USED_PERCENT LU_PROVISION_TYPE TIER_NAME LU_NAME \
This works on BOTH VIOS 2.2.3 (random order) and the future VIOS 2.2.4 (Tier then LU name order) and you get:
VIOS 2.2.3.x

Note: I have two Tiers here and they are ordered first.
A good start for two lines of ksh script but not good enough for me.
I actually need to sort the output differently for different views of the data like:
All LUs in alphabetical order so I can simply find the one I want in one go. Which LU has the larger size? Which LU is actually taking the most storage? Order on tiers then name when I want too.
etc. So here is my NEW and Improved nlu ksh script where we can order the output with options and it works on VIOS 2.2.3 and VIOS 2.2.4 with Tiers (when or if they arrive 
.
$ nlu -? /home/padmin/nlu Nigel's lu command with improved layout and column ordering /home/padmin/nlu [-sizemb | -usedmb | -used | -type | -tier | -name (default)] $
Example default output by LU Name - my favourite default

Here is the actual ksh script for nlu that is Nigel's New lu command
Runnable as padmin, root or any padmin like user (restricted shell with oem_setup_env command).
Pb with SSP
Remove cluster:
# odmget -q name=vioscluster0 CuAt # rmdev -dl vioscluster0 -R
Then you can remove hanging vhost maps
Then reboot
Where is store the config of SSP
In the folder
/var/vio/SSP/
