How to enable fc tapes for Solaris

[Adrian Gehrig]

We have to configure a Solaris 8 machine to work in a HP SAN environment. So far it works fine with the HSG80 and the presented units. Now we need to configure the tape drives for the backup. We use one FCA2257P HBA for Solaris where the tape support is enabled. There is also a modular data router with one scsi channel connected to a TL891 library and the second scsi channel connected to a MSL5026S2. Both libraries are working fine with the Windows server and the VMS Cluster also connected to the SAN. Anyone can help us with a "How-to configure FC tape drives on Solaris 8"? Thanks in advance

Well, a little mor system internals will help a lot...
The attached st.conf has to be in the /kernel/dev/ directory. There is also a config file for the HBA in the same directory, where the tape support has to be enabled...

The configuration you will made depends on the qlogic driver loaded (the FCA2257 is a qlogic 2300):

1. If the qlogic driver being used is 4.15 then it is really easy: devfsadm -C tape and you are ready !

2.If you are using older drivers, then you need to hack the qla2300.conf in /kernel/drv. You should add the WWN of the MDR on the file so Solaris know the target and the association between the target and a st device. Of course, should also modify st.conf
