library drive acces on san

[franlo]

Hello all,

I have an acces problem to my HP esl712 drives from a prolian dl585g1 via my san.

Many other servers can access to theses drives without problem.

My box is under Redhat AS 2.1 U6 with kernel 2.4.31-37 with hba qla2342 (firmware 3.03.11, driver 7.05.00-RH1-fo)

I have the following output :
- lssg
sg80 1,0,0,0 HP Ultrium 2-SCSI F59W 1000-00e0-0222-c07b
sg81 1,0,1,0 HP Ultrium 2-SCSI F59W 1000-00e0-0242-c07b

and

mt -f /dev/sg80 status
/dev/sg80: Operation not permitted


I tried with all special files /dev/st* but they don't correspond to esl drives.


Could you help me to access to my drives ?

Thanks a lot

regards
