MountV agent optional attributes (continued)<br />
Optional Attributes<br />
ForceUnmount<br />
Description<br />
Defines whether or not the agent unmounts the volume (gracefully or forcibly) when<br />
it is being used by other applications.<br />
The attribute can take the following values:<br />
■<br />
■<br />
■<br />
■<br />
NONE: The agent does not unmount the volume if an application is accessing it.<br />
READ_ONLY: The agent tries to enumerate the open handles in READ_ONLY mode<br />
to the configured mount points and then gracefully unmounts the mount points<br />
even if applications are accessing it in READ_ONLY mode.<br />
ALL: The agent forcefully unmounts the volume irrespective of the type of access<br />
an application has. The agent first tries to obtain exclusive access to the configured<br />
mount point. The agent makes this attempt twice, with half a second delay between<br />
each unsuccessful attempt. If it fails to lock the volume even after 2 attempts, it<br />
proceeds with the unmount operation.<br />
CLOSE_FORCE: The agent does not try to lock the configured mount points and<br />
proceeds directly with the forceful unmount operation.<br />
Note: Forceful unmount may potentially cause a data corruption. When you use<br />
ForceUnmount with CLOSE_FORCE, then before you switch or take the MountV<br />
resources offline, verify that none of the applications are accessing the configured<br />
mount points.<br />
Default is READ_ONLY.<br />
If you have enabled Intelligent Monitoring Framework (IMF) and fast failover in your<br />
cluster environment, Symantec recommends that you set this attribute value to ALL.<br />
This reduces the failover time as the agent does not require additional time to gracefully<br />
close the read-only handles on the volume.<br />
Type and Dimension: string-scalar<br />
ListApplications<br />
Defines whether the agent lists the applications accessing the volume while unmounting.<br />
The value 1 indicates that the agent lists the applications; the value 0 indicates that it<br />
does not.<br />
Default is 0.<br />
If you have enabled Intelligent Monitoring Framework (IMF) and fast failover in your<br />
cluster environment, Symantec recommends that you set this attribute value to 0.<br />
This reduces the failover time as the agent does not enumerate the applications that<br />
are accessing the volume.<br />
Type and Dimension: boolean-scalar
