Restore ESM and ELM data to a new hardware.

Hi All,

Recently we had a hardware failure on our SIEM appliance. Following are the details

ENMELM-6000   Combo box with a DAS-10 Storage.

A backup of ESM settings and ELM management database is available. The ELM data is intact on the DAS.

On the RMA box, we have performed the following operations.

1. Brought the Firmware to the old box level.

2. Restored the ESM Configuration data. This happened successfully and all the data sources and policy settings are restored.

3. Disconnected the DAS box from the Old Hardware & Connected to the new hardware.

4. The DAS drive is visible in the CLI and the data files are visible.

However the ELM settings are not restored, and no storage pools are visible in the ELM Configuration. The ELM Management database is available in an NFS storage.

Advise is needed on how to restore the ELM management database and ELM settings to view the raw logs.

Re: Restore ESM and ELM data to a new hardware.


The ESM backup file contains ERC, ACE backup, but it does not include ELM.

There is a backup for ELM, restore it.


You should also follow the steps below.

1. Brought the Firmware to the old box level. (also software version)

2. Disconnected the DAS box from the Old Hardware & Connected to the new hardware.

3. Restore the ESM Configuration data.

4. Wait until GUI login becomes available

4. Reboot. (Requires reboot after restore)

5. Restore the ELM Configuration data.

6. Wait about 30 minutes.

7. Reboot. (Requires reboot after restore)
