iXOS-JUKEMAN 2.2 User Manual Pre.12/97250
The next symbol specifies the type of process that issued the command.
The process symbols are:
@ controls a drive. It actually reads the data requested by clients.
% controls a changer. For simple jukeboxes it may also control the
drive.
? accepts NFS requests and replies immediately or queues them.
$ accepts internal requests to support the native file system of the
NT version.
# schedules the requests from ? and $ and passes them to % and @.
& creates and terminates the threads @ and % upon request of #.
- is a @ or % process during asynchronous task processing.
~ is a portmapper which is started if the operating system does not
run a portmapper (see the description of the waitpm server pa-
rameter, page 123).
^ monitors manual disk changes in single drives and towers (see
the description of the dcheck server parameter, page 123).
= accepts cdadm requests via TCP/IP.
After the process type, a digit or letter may follow. Non-trivial requests that
cannot be satisfied quickly from cache are assigned these digits or letters
cyclically. This simplifies the task of tracing a single user request through
the large file of a busy server. A blank indicates that no specific request
caused the action. Finally, there is the individual log message. This may,
for example, report that a specific piece of hardware was detected, or that
the server found a disk. Disk names are reported in rr and pc format.
A large class of messages are SCSI error reports:

Here the server reports an error that ocurred during a SCSI READ com-
mand on a disk. The first line reports the complete SCSI command: Ten
bytes that were sent to the drive. The next line reports the command key,
28 hexadecimal, with the SCSI command name, the 10-byte version of the
