x_cons <database_name> show cport
Shows registered completion ports and pending I/O on them. The display is similar to command "show iopending", but shows only I/O on completion ports.
- O: operation ('F'=format, 'w'=write, 'r'=read, 'W'=multi-write, 'R'=multi-read, 'S'=stream operation on backup medium, 'o'=open volume, 'c'=close volume, 'O'=open stream, 'C'=close stream, 'I'=initialize tape)
- Flg: Flag ('A'=asynchronous I/O, 'C'=I/O on cport, '+'=high priority I/O, '-'= low priority I/O, No flag = medium priority I/O)
- Device: Path to device
- Owner: Owner task of the I/O
- Worker: Either I/O worker name working on the operation or self I/O if the task does the I/O by itself inline.
- BlkPosit.: Starting block position on volume, where the I/O occurs.
- QueueID: Queue ID of I/O subsystem (each volume has several queues)
- BlkCount: Requested count of blocks in the I/O, usually starting from BlkPosit, except for multi-I/O, where they can be scattered.
- BlkCompl.: The number of already completed blocks, here we can see formatting progress for instance.
- State: Status of the I/O operation.
I/O job status
- Pending: pending
- InProgress: in progress
- Success: success
- Failed: failed
- RetSucc: retired successfully. Per I/O context, some history of retired operations (by default 8), so we can see what each task has done in the past time. (see parameter RetiredIOJobCount)
- RetFail: retired failed
- Cancelled: cancelled
