Hi,

    We had a problem when a disk shelf failed. The error message is as
follows:

Mar 23 15:33:09 freebsd /kernel: isp0: bad underrun for 0.0 (count > 65536,
resid 2147422207, status not marked)

I would like to know the reasons of what causes Data Underruns in FC Adapters?
Any pointers?


Thanks,
Rajesh
