Maintenance
1. Maintenance Service
Service representatives subordinate to or authorized by NEC provide services of the disk
array controller with use of genuine parts and high technical capabilities. You can get the
services for your own convenience.
For the services, contact the NEC sales department or representatives.
2. Preventive Maintenance
2-1. Data Backup
In case of an unexpected accident, it is recommended to back up data in HDDs routinely.
For the data backup, refer to the User’s Guide of the server.
2-2. Preventive Maintenance by Media
Patrol/Synchronization
It is recommended to perform media patrol or synchronization routinely as preventive
maintenance against subsequent defects of HDDs. These features allow subsequent
defects of HDDs to be found and repaired as soon as possible. Both the features can be
done routinely by using the scheduling function of WebPAM.
For details of the media patrol and synchronization, see "Chapter 3 Features of Disk Array
Controller."
The recommended scheduling interval is once per week. Depending on the operation
status of your system, the scheduling interval should be at least once per month.
Check
To utilize the media patrol or synchronization, WebPAM must be installed.
