gl command

The gl command displays or removes group locks.

Syntax

gl{-}

With no options, the monitor prints the status of the global group lock (with a G+ or a G-), and scans memory for any frames that are marked as locked. For each locked frame, the monitor displays the FID, the address of the buffer table entry, and all group lock information held in the frame itself.

To clear all group locks, type gl-.
To clear a specific group lock, type gl-{fid}.

Note: Locks cleared from the monitor debugger can still display with the list-locks command. Such locks should be cleared with a clear-locks command when the virtual machine becomes accessible. In general, group locks should always be cleared with TCL commands only. The monitor debugger should only be used when system access is denied due to a lock set on a critical file (for example, the mds,, file).
