Set up a second ELM storage device to mirror the data collected on the main device.
If the main device goes down, the backup device continues storing the data as it comes in. When the main device comes back on line, it automatically syncs with the backup, then resumes storing the data as it arrives. If the main device goes down permanently, you can reassign the backup to become the main on Trellix ESM, then designate a different device to mirror it.
When either device goes down, a health status flag .png "flag.png")
appears next to the ELM device on the system navigation tree.
A mirrored storage pool might lose connection with its storage device. The loss can be due to:
The file server or the network between the ELM and the file server has failed.
The file server or network is shut down for maintenance.
An allocation file is accidentally deleted.
When there is a problem with the mirror, the storage devices show a warning icon .png "GUID-AE2E89A3-D8EC-4E2D-A9B4-6A6707FDFD1A-low.png")
in the Storage Pools table. Use the Rebuild function to repair it.
