While an HSM file system is operating in Limited Access Mode, do not invoke the

fsefile --recallcommand in order to recall offline files. In this operational mode offline files should not be recalled manually.

Switching to Limited Access Mode

Prerequisites

FSE processes on the FSE server and the FSE client must be running.

The HSM file system must be operating in FAM.

To switch the HSM file system access to LAM, use the fse command and specify the name of the corresponding disk volume:

C:\>fse --limit-access VolumeName

Switching to Full Access Mode

Prerequisites

FSE processes on the FSE server and the FSE client must be running.

The HSM file system must be operating in LAM.

To switch the HSM file system access to FAM, use the fse command and specify the name of the corresponding disk volume:

C:\>fse --full-access VolumeName

For more information on the HSM file system access modes, see ”HSM file system access modes” on page 148.

Limited Access Mode error messages

When an HSM file system is operating in Limited Access Mode, if access to an offline file or modification of HSM FS contents is denied to a third-party application, the application displays its own error message. Different applications therefore report different error messages.

Command prompt (after the Windows’ native copy command is invoked)

Incorrect function (0) files copied.

Windows Explorer (after an offline file is pasted or dragged over to another location)

Invalid MS-DOS function

NOTE: For information on how to determine the access mode for a particular HSM file system or troubleshoot potential problems with disk volume access, see description of the fse command in the FSE command-line reference.

Monitoring FSE jobs

FSE provides facilities to monitor FSE jobs that are currently running in the FSE implementation. You can use either FSE command-line interface or FSE Management Console to list and view statuses of FSE jobs. When using FSE command-line interface, you can also narrow your query to list only jobs of a particular type.

Listing FSE jobs

To list FSE jobs using the FSE command-line interface, run the following command:

fsejob --list PartitionName [--detail]

The following job properties are displayed:

job ID

name of the FSE partition for which the job is running
