Hi, I've got a Compaq DL320 server here, with a SmartArray 532 SCSI/RAID controller in it. The "ciss" driver detects the logical RAID volume attached to the controller, but it does not detect the two DLT tape drives attached to it on the external port. However, they are detected by the BIOS on boot, so there is nothing physically wrong (all terminated, cabled correctly, etc). From my reading of the "ciss" driver source, the driver only supports logical drives, i.e. disk arrays. Although the tape drives are supported by the card, they are not supported by the driver. Is this correct, and if so, is it likely to change? I'd love to know if anybody has gotten tape drives working on a ciss-supported card. I'd hate to have to put Linux on the box just to get tape support in the driver. :( System: 4.6-STABLE as of August 27, driver source hasn't noticeably changed in 4.7-RELEASE either (I checked). camcontrol is of no help whatsoever, it just reports the logical drive. Thanks for any help, Paul Radford relevant dmesg: ciss0: <Compaq Smart Array 532> port 0xb000-0xb0ff mem 0xd0500000-0xd0503fff,0xd0000000-0xd003ffff irq 3 at device 1.0 on pci1 ciss0: using 256 of 1024 available commands ciss0: 1 logical drive configured ciss0: firmware 1.16 ciss0: 2 SCSI channels ciss0: signature 'CISS' ciss0: valence 1 ciss0: supported I/O methods 0xe<simple,performant,MEMQ> ciss0: active I/O method 0x3<simple> ciss0: 4G page base 0x00000000 ciss0: interrupt coalesce delay 1000us ciss0: interrupt coalesce count 16 ciss0: max outstanding commands 1024 ciss0: bus types 0x2<ultra3> ciss0: server name '' ciss0: heartbeat 0x10000026 ciss0: 1 logical drive ciss0: logical drive 0: RAID 1, 16896MB online To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
