System Disk Data Loss

Publication Date:  2012-07-19 Views:  303 Downloads:  0
Issue Description
The system disk data is lost.
Alarm Information
Handling Process
Step 1 Set the write mode of the system disk to write-though.
Step 2 If the problem persists, contact Huawei Symantec technical support engineers.
Root Cause

Possible Causes
The RAID card battery is not provided in the basic configurations of the VTL3500.

When the write mode of the system disks is write-back, the data in the cache cannot be written
into the disk when a power failure occurs; therefore, the data is lost.
