hello, i have 2 FAS980C's in my SAN environment. Data on one is mirrored to the other. i have twice experienced link breaks on two of my hba's adapter 5b and 6b on both filers at the same time, the links come up at the same time after about 7mins. both times when this has happened, our Exchange server looses access to its SAN disk devices leading to a downtime. Has any body experienced this before, if so please HELP me prevent this from happening again. here is error log: Wed Nov 29 13:50:19 GMT [vhe-cl1-n1: scsitarget.ispfct.linkBreak:warning]: Link break detected on Fibre Channel target adapter 5b.
