EVM error scanSCSIBus: Could not find path(s) to new device with LUNWWID ...

[Van Cotoco]

I have EVM 2.0d manager on a SAN Management Appliance doing a clone of a volume in an MA8000 storage. The EVM job is supposed to clone, then split the BCV,and then mount the BVC to a Windows NT4.0 server. The job completed up to the point where the BCV was made. When the EVM job attempts to mount the BCV to the Windows server, the error "could not find path ..." was returned.
The Windows server is visible on the SecurePath Manager. It has EVM 2.0d host agent running on it and SecurePath 4.0.
After the BCV is split, manually running Disk Adminstrator on the Windows server will enable me to assign the BCV a drive letter, and it becomes useable.
What could be the cause of the problem?

A) I hope you are using SecurePath 4.0C rather than 4.0

B) Make sure all the paths from the server (zoning cards, cables etc.) not just the redundant ones work as from the error message it seems that it can find some but not others.

C) The server is picking up an old drive signature that it knew about previously from the disk, i.e. not for clone use but for another purpose (mirror). Clean off the old signature from the disk (using DILX if you are sure that you don't destroy everything else) or dumpcfg (command line utility from the NT4 resource tools) to write a spoof signature on the BCV.

Then rerun the evm job.

Hi, it's been a year before I got to upgrading the SecurePAth to 4.0c. I'm still getting the same error though I checked the SecurePath is working properly.
I see the following errors in the sb log of the server where the BCV is supposed to be mounted:

Thanks for your help.
