Package: linux-image-2.6.22-4-amd64 Version: 2.6.22-6~bpo40+2 Severity: minor
When I log into a Dell MD3000i disk array using iscsiadm, I see the two volumes that I've configured show up as scsi disks, which is as it should be: Feb 21 21:35:10 localhost kernel: scsi1 : iSCSI Initiator over TCP/IP Feb 21 21:35:10 localhost kernel: scsi 1:0:0:0: Direct-Access DELL MD3000i 0670 PQ: 0 ANSI: 5 Feb 21 21:35:10 localhost kernel: sd 1:0:0:0: [sdc] 4269801472 512-byte hardware sectors (2186138 MB) Feb 21 21:35:10 localhost kernel: sd 1:0:0:0: [sdc] Write Protect is off Feb 21 21:35:10 localhost kernel: sd 1:0:0:0: [sdc] Mode Sense: 77 00 10 08 Feb 21 21:35:10 localhost kernel: sd 1:0:0:0: [sdc] Write cache: enabled, read cache: enabled, supports DPO and FUA Feb 21 21:35:10 localhost kernel: sd 1:0:0:0: [sdc] 4269801472 512-byte hardware sectors (2186138 MB) Feb 21 21:35:10 localhost kernel: sd 1:0:0:0: [sdc] Write Protect is off Feb 21 21:35:10 localhost kernel: sd 1:0:0:0: [sdc] Mode Sense: 77 00 10 08 Feb 21 21:35:10 localhost kernel: sd 1:0:0:0: [sdc] Write cache: enabled, read cache: enabled, supports DPO and FUA Feb 21 21:35:10 localhost kernel: sdc: unknown partition table Feb 21 21:35:10 localhost kernel: sd 1:0:0:0: [sdc] Attached SCSI disk Feb 21 21:35:10 localhost kernel: scsi 1:0:0:1: Direct-Access DELL MD3000i 0670 PQ: 0 ANSI: 5 Feb 21 21:35:10 localhost kernel: sd 1:0:0:1: [sdd] 1586597888 512-byte hardware sectors (812338 MB) Feb 21 21:35:10 localhost kernel: sd 1:0:0:1: [sdd] Write Protect is off Feb 21 21:35:10 localhost kernel: sd 1:0:0:1: [sdd] Mode Sense: 77 00 10 08 Feb 21 21:35:10 localhost kernel: sd 1:0:0:1: [sdd] Write cache: enabled, read cache: enabled, supports DPO and FUA Feb 21 21:35:10 localhost kernel: sd 1:0:0:1: [sdd] 1586597888 512-byte hardware sectors (812338 MB) Feb 21 21:35:10 localhost kernel: sd 1:0:0:1: [sdd] Write Protect is off Feb 21 21:35:10 localhost kernel: sd 1:0:0:1: [sdd] Mode Sense: 77 00 10 08 Feb 21 21:35:10 localhost kernel: sd 1:0:0:1: [sdd] Write cache: enabled, read cache: enabled, supports DPO and FUA Feb 21 21:35:10 localhost kernel: sdd: unknown partition table Feb 21 21:35:10 localhost kernel: sd 1:0:0:1: [sdd] Attached SCSI disk Feb 21 21:35:10 localhost kernel: scsi 1:0:0:31: Direct-Access DELL Universal Xport 0670 PQ: 0 ANSI: 5 I also see it attempt to bring up a third "disk", which is actually the in-band management interface, and I see a number of I/O errors as it tries to read the partition table: Feb 21 21:35:10 localhost kernel: sd 1:0:0:31: [sde] 40960 512-byte hardware sectors (21 MB) Feb 21 21:35:10 localhost kernel: sd 1:0:0:31: [sde] Write Protect is off Feb 21 21:35:10 localhost kernel: sd 1:0:0:31: [sde] Mode Sense: 77 00 10 08 Feb 21 21:35:10 localhost kernel: sd 1:0:0:31: [sde] Write cache: disabled, read cache: enabled, supports DPO and FUA Feb 21 21:35:10 localhost kernel: sd 1:0:0:31: [sde] 40960 512-byte hardware sectors (21 MB) Feb 21 21:35:10 localhost kernel: sd 1:0:0:31: [sde] Write Protect is off Feb 21 21:35:10 localhost kernel: sd 1:0:0:31: [sde] Mode Sense: 77 00 10 08 Feb 21 21:35:10 localhost kernel: sd 1:0:0:31: [sde] Write cache: disabled, read cache: enabled, supports DPO and FUA Feb 21 21:35:10 localhost kernel: sde: unknown partition table Feb 21 21:35:10 localhost kernel: sd 1:0:0:31: [sde] Attached SCSI disk Feb 21 21:35:11 localhost kernel: end_request: I/O error, dev sde, sector 48 Feb 21 21:35:11 localhost kernel: Buffer I/O error on device sde, logical block 6 Feb 21 21:35:11 localhost kernel: Buffer I/O error on device sde, logical block 7 Feb 21 21:35:11 localhost kernel: Buffer I/O error on device sde, logical block 8 Feb 21 21:35:11 localhost kernel: Buffer I/O error on device sde, logical block 9 Feb 21 21:35:11 localhost kernel: Buffer I/O error on device sde, logical block 10 Feb 21 21:35:11 localhost kernel: Buffer I/O error on device sde, logical block 11 Feb 21 21:35:11 localhost kernel: Buffer I/O error on device sde, logical block 12 Feb 21 21:35:11 localhost kernel: Buffer I/O error on device sde, logical block 13 Feb 21 21:35:11 localhost kernel: Buffer I/O error on device sde, logical block 14 Feb 21 21:35:11 localhost kernel: Buffer I/O error on device sde, logical block 15 I'm not sure if this is something the enclosure is reporting oddly that there's no way for the kernel to get right. It's also easily work- around-able by simply disabling the in-band management interface in the Dell tools. Nonetheless it seems that in a perfect world, this interface would be detected for what it is and not exposed as a disk (even if it's not going to be exposed as a management interface either). FWIW, the iSCSI subsystem maintainer has said that this is something that needs to be addressed in the scsi subsystem, and not anything he has direct control over from the iSCSI layer.
