FC tape drive configuration on Redhat AS

Nappy_1 — Wed, 11 Jun 2008 06:41:59 GMT

i have 4 FC tape drives (LTO4) connected to redhat AS 4 through a brocade switch
the server is using 2 qlogic ql2462 hba cards

the sansurfer tool is able to see the 4 devices but don't know where is the device files related to them.

so where are the device file? if they don't exist how to do to create them?
how can i test the tape drives to be sure they are well configured?

>>> so where are the device file? if they don't exist how to do to create them?

Device files should be created after detected. You should see /dev/stX /dev/nstX.

Try with hp_rescan -a. You should install the support pack if this is a proliant server.
