DiskReservation agent notes

The DiskReservation agent has the following notes:

• The DiskReservation agent does not reserve disks that have multiple paths
• Configuring the MonitorTimeout attribute for more than three disks

The DiskReservation agent does not reserve disks that have multiple paths

You cannot use the DiskReservation agent to reserve disks that have multiple paths. The LVMVolumeGroup and the LVMLogicalVolume agents can only be used with the DiskReservation agent, Symantec does not support the configuration of logical volumes on disks that have multiple paths. To ensure data protection on such a configuration, Symantec recommends the use of Veritas Volume Manager (VxVM) disk groups. Note that VxVM requires the use of SCSI-3 compliant disks.

Configuring the MonitorTimeout attribute for more than three disks

The MonitorTimeout attribute's setting of 60 is adequate for up to three disks. When configuring the MonitorTimeout attribute for more than three disks, use the following formula:

Set MonitorTimeout to be equal or greater than 15 times the total number of disks. (MonitorTimeout >= 15 * Number of disks).

For example, if you have eight disks, MonitorTimeout is 120 or greater.
