NAME
acl_status_library - get current ACL status information and SCSI sense data.
SYNOPSIS
acl_status_library -stdout <output_spec> [ -device device_special_file ] [ -n ]
[ -retry_on_reset ]
acl_status_library -help [ help_type ]
DESCRIPTION
acl_status_library issues a SCSI Request Sense command to the ACL to retrieve the current
Sense Data. This utility is usually used to determine the condition(s) that caused the previous
utility to fail.
• The ACL clears Sense Data prior to executing any SCSI command other than Request
Sense and sets Sense Data when a command results in Check Condition or Command
Terminated status. Separate Sense Data is preserved for each initiator. Sense Data is
cleared after it is retrieved by a Request Sense command.
• In general, the ACL retains the original Sense Data when an error occurs executing a
Request Sense command. However, when the error occurs parsing the command
descriptor block (CDB), the original Sense Data is lost and is replaced with Sense Data
corresponding to the parsing error
The -stdout <output_spec>specifies the output fields written to stdout.
acl_status_library is available to all users. See the acl_intro(1) manual page for ACL naming
conventions and general information on command-line options and arguments.
OPTIONS
-device device_special_file
Specifies the device special file to use for the operation.
-n
Prevents the utility from appending a trailing newline to the output stream written to stdout,
but does not affect newlines embedded in the output stream.
