Arun,

We ran into a similar problem at our site.  We were using Qlogic cards an 
E420 to talk to the SAN with SSO , the other
media servers were W2K with another brand of HBA card.  After carefully 
setting up the binding information, we would lose
 the binding after every re-boot of the Solaris system.  Our Veritas guy 
said that is is not a good idea to mix vendors for
HBA cards. 

We ended up choosing another option and decided not to use the Solaris box 
as a media server with the SSO. 

This probably doesn't help much, but at least you know you aren't alone.

Many things could cause the backup delay.  Be sure it is not a network 
issue by checking your NIC settings.
You may need to configure for 100FDX with no autonegotiate for your 
switches.

Hi All,
Recently our Sun V480R running Solaris 8 was configured for NB 4.5. We 
have done persistent binding for Crossroad routers with the Qlogic HBA's. 
Every thing is running fine, when i run 'sgscan' i can see the list of all 
my 14LTO drives but once i do a reboot on the server, the LTO's are not 
visible to 'sgscan' though /dev/sg has all the entries. Now i am running 
'sg.install' and getting back the LTO's visible to 'sgscan', i am doing 
this on every reboot. Has any one encountered the same problem before or 
am i missing something to do after running sg.install ?
Since yesterday i'm facing another problem i.e. a delay of more than 8 
minutes in bringing the backups to queue state after initiating, although 
my restores are starting within seconds period of time. Any help/comments 
is appreciated.
Thanks in Advance
-Arun 


Have a great day!!
