I received couple of mails, now that we have decided to go for a unique vendor 
probably JNI HBA cards. Thanks for all your suggestions and support.

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
