Support for Remote Command Device
Metrocluster with Continuous Access XP P9000 for Linux includes support for remote command
device. A remote command device is a device to which a command device in a remote P9000
array is mapped. A remote array P9000 RAID Manager must be configured using the remote
command device. Using a remote array RAID manager instance, it is possible to get the status of
the device group on the remote P9000 array even when the remote hosts are inaccessible.
The remote command device can be configured using one of the following methods:
• Using the P9000 external storage feature
• Using an extended SAN
