Status in Cinder: Fix Released Status in OpenStack Compute (nova): Fix Released Status in os-brick: Fix Released Bug description: As part of POC for an enterprise storage we have implemented an ISCSIDriver. Volume operation works as expected. Facing an issue with attach volume. Request your help. 1. If the volume lun id in backend storage is less than 255 attach volume works fine. Symlinks in /dev/disk/by-path is as below lrwxrwxrwx 1 root root 9 Jun 18 15:18 ip-192.168.5.100:3260-iscsi-iqn.1989-10.jp.co.xyz:storage.ttsp.2ec7fdda.ff5c4a16.0-lun-169 -> ../../sde lrwxrwxrwx 1 root root 9 Aug 26 14:47 ip-192.168.5.100:3260-iscsi-iqn.1989-10.jp.co.xyz:storage.ttsp.2ec7fdda.ff5c4a16.0-lun-172 -> ../../sdi 2. If volume lun id is more than 255, /dev/disk/by-path is an hexadecimal number and hence attach volume is failing with message Volume path not found. Symlinks in /dev/disk/by-path is as below [hexadecimal lun id according to SCSI standard ( REPORT LUNS)] lrwxrwxrwx 1 root root 9 Aug 26 14:47 ip-192.168.5.100:3260-iscsi-iqn.1989-10.jp.co.xxx:storage.ttsp.2ec7fdda.ff5c4a16.0-lun-0x016b000000000000 -> ../../sdh lrwxrwxrwx 1 root root 9 Jun 18 15:18 ip-192.168.5.100:3260-iscsi-iqn.1989-10.jp.co.xxx:storage.ttsp.2ec7fdda.ff5c4a16.0-lun-0x0200000000000000 -> ../../sdc Please provide your suggession. I would suggest cinder utility to have a check of both with normal lun-id in /dev/disk/by-path as well as hexadecimal lunid.
