We have an issue with WWN dropping out of the name server. This is on our TAN fabric. Tape backup SAN. Their are 6 switches in this fabric. Brocade and IBM 3800 and 3900 series. Switch in question is an IBM 3900 F32, a Tape Edge switch connected to IBM LTO Gen1 (3583) tape drives. We run Legato backup software. When a backup recieves a data check (media error), drive will drop out of name server. Only power cycle of tape drive will allow drive to log back in to NS. Code on switch is 4.2.0b. Any thoughts on how to relolve this issue?
