Re: [CentOS] Problem detecting HP Tape Drive
Solved! The answer is: echo engage scsi /proc/drivers/cciss/cciss1 With that thing everything worked fine.

Re: [CentOS] Problem detecting HP Tape Drive
Dear All thanks for the replies Rainer That's a tape not a SAN, and there is no fiberchannel. Just an SCSI tape attached to outside ports of an LSI SCSI adapter(a pci card). Does that something to do with hp_rescan utility? Isn't hp_rescan only for Emulex HBAs? If not, Where could I find the rpm or tgz package? John R Pierce I don't think that SCSI ports outside(behind) the server chasis be for smart arrays? Are you sure? -- Mehdi Sarmadi On Sat, Jan 3, 2009 at 11:59 PM, Rainer Duffner rai...@ultra-secure.de wrote: Am 03.01.2009 um 20:54 schrieb Mehdi Sarmadi: Hello I do have problem using Linux with an external HP tape drive.

Maybe it's only for SAN-stuff, but maybe it also works in this case. cheers, Rainer ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
