Are there are any dtrace scripts available to trace data to and from HBA? I am having issues where average R/W time on one of the path goes 10-15 times higher than the other one causing major performance issues. BTW, it does not happen consistently and the bad performance becomes much more obvious during SAN disk to SAN disk system backups. This is happening on multiple servers.
Appreciate any help in this regard in advance.
