I am having issues with the Exchange verification process when the remote verification service runs on a VM. The ESX 3 server has the NetApp FCP host kit but I keep on getting the FCP partner misconfigured error. I can not yet upgrade to vSphere so I have a cron job which sets the MPIO path every hour. However this is not enough for the verification job as it has 8 luns in two volumes.
Any advise please?

This is the filer error:
FCP Partner Path Misconfigured - Host I/O access through a non-primary and non-optimal path was detected.

This is how I made the pain go away for the none SME/SMSQL verification
ESX servers. What you want is in step 4).
Hope it helps
Does not work with verification due to luns mounting and unmounting all
the time during the jobs. Think setting the cron to every 1 minute
would address the issue but that is a very ugly solution.
1. Log into the ESX host's Service Console with root/su permissions.
2. Run the command vi /etc/crontab
root@esxserver etc]# vi /etc/crontab
01 * * * * root run-parts /etc/cron.hourly
02 4 * * * root run-parts /etc/cron.daily
22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly
3. Go to the end of the last line of the file by using arrow keys. Press
the 'a' key to change to INSERT mode.
4. Press Enter to start a new line in the file. The first number in the
string will determine what minute past the hour the script will run.
This example shows the command running hourly at 5 minutes past the
hour. The config_mpath options can also be modified to fit your needs
(example: adding --secure would ensure that the script runs over SSL):
5 * * * * root echo "config_mpath --primary --persistent --policy
5. Press the ESCAPE key to exit INSERT mode.
6. Press the colon ':' key, then 'wq'
7. Press enter to save the changes to the file.

When setting the preferred path through the FCP utilities did you set the primary, persistent, and load balancing policy? Once setting this it fixed our misconfigured path.
config_mpath --primary --loadbalance --persistent --policy fixed

The partner misconfigured error could be a couple of different thing. It could be something as simple as a configuration issue or it could also mean that the primary path between the host and the storage has failed. Is this something that happens only during verification or at other times as well such as during the SnapMirror process. Is this just something that is failing during the verification process?
Sorry I couldn't provide more details,

Verification was failing due to a mis-configured Riverbed 'playing' with the snapmirror traffic. This has been sorted and I am just left with intermittent fcp errors but everything is working.
Thanks for the help anyway
