| Known issues and unimplemented features |
| --------------------------------------- |
| |
| - NPIV targets not quite work. If you need NPIV, use QLogic git driver |
| |
| - Minor "ToDo"'s spread in the code. |
| |
| Very old and, probably, already fixed: |
| |
| - If a Linux initiator asks for devices using INQUIRY command too soon |
| before the controller on the 23xx target is fully initialized in the |
| target mode, the initiator could receive garbage devices and the |
| messages "scsi: unknown device type 31" will be printed in the kernel |
| log on the initiator. After rescan on the initiator (eg by |
| rmmod/modprobe the driver) the correct devices will be added instead |
| of the garbage ones. This is actually Linux SCSI mid-level's problem |
| (although also could be the Qlogic firmware's one): type 31 is |
| "unknown or no device type", but the SCSI mid-level treats such |
| devices as real and adds them to the system. To avoid it, try to |
| leave the target enough time for initialization (some 10th seconds). |
| With the latest firmware that might be fixed. |
| |
| - On 23xx if on a tape with block size 0 we write block with size X |
| and then read it with bs <X the tape skips all blocks with size X |
| until the next correct block or filemark found, instead of returning |
| ILI with negative counter. Looks like the initiator retries the |
| command quietly. 22xx works correctly. With the latest firmware that |
| might be fixed. |
