if that failure status is true, that's not a good thing ..support will probably want to run background verify on those LUNs and see what's going on. Have good backups of data on those LUNs ?

Thanks Dynamox for your quick response, in fact i don't know where to find this message u just replied by.. on the other hand the message i have is in the Unisphere Gui, under migration, when i choose the failed session and click status, under the copy tab, this appears to be the status details: The Session failed because either the source or all destinations have failed. Check the device that failed and the path to it. For a device on a remote storage array, verify the zoning and ensure that it is in the correct storage group
then under the source tab, it says: a bad block was encountered on the source device.

Yeah i guess that's the case, i did some reading and as u said it appears that a background verify needs to be done.thanks for ur support dynamox. most appreciated.

Adding to what dynamox already mentioned, if you intend to use replicated data for restore/recovery. Please, also ensure the data integrity by means of host-based application-level data integrity mechanisms.
Thanks,
Ankit
