I am in the middle of a migration from EMC storage to NetApp storage and am slowly losing my mind. To stave off a visit the funny farm for as long as possible I have written a couple scripts that have lessened the pain considerably.
When I was using PowerPath for the EMC LUNs I was able to use the powermt command to get detail. Because PowerPath is incompatible with NetApp LUNs I have had to remove PowerPath and rely on MPIO. With that shift all of the nice things that came with PowerPath vanished. I am left with looking at LUNIDs and lsdev -type disk commands to determine which LUN is which.
To aid in that determination I have written the following two scripts. The first one is is a simple korn shell script to list all of the hdisks along with their LUNID. I placed it in /usr/local/bin on the VIO servers and then, to make it handy added an alias in .profile to execute it easily.
Here is the script:
# cat /usr/local/bin/lslunids
#!/bin/ksh
for i in `lspv | grep ^hdisk | awk '{print ($1)}'`
do
echo "$i\tLUNID=\c" ;
lsattr -El $i -a lun_id | awk '{print ($2)}' | \
sed "s/^0x\(..\)000000000000/\1/" | \
sed "s/^0x\(.\)000000000000/0\1/" | \
sed "s/0x0$/00/" | \
awk '{print $1" : "("0x"$1)+0}'
done
Here are our mods to .profile:
$ head -20 .profile
export PATH=/usr/ios/cli:/usr/ios/utils:/usr/ios/lpm/bin:/usr/ios/oem:/usr/ios/ldw/bin:$HOME
# Start Modifications
PS1='[pSeriesHost-VIO1] \$ '
export PATH=$PATH:/usr/local/bin
export ENV=.kshrc
set -o vi
alias aix="oem_setup_env"
alias showluns="echo 'sanlun lun show' | oem_setup_env "
alias lslunids="echo '/usr/local/bin/lslunids' | oem_setup_env "
stty erase ^?
# Stop Modifications
The output looks like:
$ lslunids
hdisk3 LUNID=00 : 0
hdisk0 LUNID=00 : 0
hdisk1 LUNID=01 : 1
hdisk2 LUNID=02 : 2
hdisk4 LUNID=03 : 3
hdisk5 LUNID=04 : 4
hdisk6 LUNID=05 : 5
hdisk7 LUNID=06 : 6
hdisk8 LUNID=01 : 1
hdisk9 LUNID=02 : 2
hdisk10 LUNID=03 : 3
While this was hugely helpful it is still too simple. For example if you look carefully above you will see LUNIDs that are duplicated. That is because one is being offered by the NetApp and another is being offered by the EMC. So you have to do something like: lsdev -type disk | grep "hdisk1 " to see who is serving the LUN.
$ lsdev -type disk | grep "hdisk1 "
hdisk1 Available MPIO NetApp FCP Default PCM Disk
$ lsdev -type disk | grep "hdisk8 "
hdisk8 Available EMC CLARiiON FCP MPIO RAID 5 Disk
It is a pain.
So a new script is born and it runs on your workstation (assuming you are smart enough to be running Linux as your workstation ;-) Or from any Linux/Aix box you have access too. It simply requires Perl and SSH.

Balancing LPAR paths in dual VIO enviornment
I have been using LPARs for a very long time and it has always bothered me that the distribution of I/O was unbalanced. I use two VIO servers for redundancy. Each VIO server supplies a path to a disk. This way if a VIO server, HBA or fiber switch fails, access to the disk is preserved.
The problem is that when paths are assigned to a disk on the LPAR they are done in a very uniform pattern and you wind up with ALL of your I/O going to a single VIO server. Multiply this across all LPARs and you have one very busy VIO server and one sitting back twiddling its bits.
You can see this very easily using tools like isstat -m and nmon using the "a'" option. I prefer nmon.
Here is what it looks like on the LPAR.

As you can see the two vscsi devices both have I/O going through them. If you install nmon on your VIO server, you can see the same thing there only it will be the actual HBAs.
I accomplished this by running the script below. In a nutshell, it works under the assumption that statistically there will be a roughly equivalent number of evenly numbered hdisks as odd. The evenly numbered disk are set to prefer one path and the odd numbers the other. It also assumes that there are only two VIO servers.

Fiber Switch Migration
I searched the web and found nothing so decided to document publicly a procedure that has been tested that will allow a person to migrate a system running AIX, using ESS/Shark storage from one fiber switch to another without incurring a downtime.
Start with seeing what the paths are to start with. Below we can see that each LUN has 4 paths.
Get a list of the fiber channel HBA devices

root(pshrdb1):/usr/bin>lscfg | grep fcsTake one of the paths off line. It is not important which one. We will check for a “dark” HBA by visually inspecting the back of the box. In this example we will be oflineing and removing fcs0 witch is the HBA plugged into slot 3 (...-C3-... above)

We can now see that some of the paths are now gone. In this example, each LUN went from having 4 paths to only having 2.

root(pshrdb1):/usr/bin>lsvp -aAll of the paths have been removed from fcs0 so we are going to delete the device. We do so recursively so that it will automatically remove any dependent device.

root(pshrdb1):/usr/bin>rmdev -dl fcs0 -RHere go identify the HBA that is showing no traffic. In this example it will be in slot 3. It should have a slow blinking green light but no amber light. You can now redirect the fiber from the old switch to the new switch for this HBA.

Make sure you have zoned the new switch so that the host and the storage are visible to each other.
Do not proceed below until you have accomplished the fiber move and zoning.
Run cfgmgr to re-discover the deleted HBA and establish a path to the new fiber switch.
