[Veritas-bu] Sg / sgen driver issue

 


Thanks to everyone who responded to my posting.

Turned out that it was NSR.e1200 router configuration in the HP MSL5060 tape
library that I needed to change. My previous admin. had configured the
router with some WWN-mapping (like the soft zoning in FC switches) to bind
it to only specific server's HBA, so that's why I couldn't see all the
drives correctly no matter what I tried, although my OS & NBU configs all
seemed perfect.

I thought about this possibility with NSR.e1200 but was reluctant to touch
this and this made me delay my backup server migration almost 3 weeks!

All the problems I had (initially) w/ fiber zoning was my initial setup of
the brocade switch.  After that you just use the cfgadm commands and be on
your way.
