Data Integrity Check and RAID Manager

Data Integrity Check is configured and operated using Data Integrity Check commands in RAID
Manager XP. For RAID Manager operations, refer to the

HP StorageWorks RAID Manager XP User’s

Guide.

You must specify the volume to be checked, and the type of check using RAID Manager (the types
are different depending on versions). The files (constructed in RAW volume) that are checked are:
Data, Redo log and Control. If data is written from the host server to the array, the data check is
initiated by channel adapters (CHIPs) that support Data Integrity Check.

NOTE:

The check is not started when the data is read.

When invalid data is detected, the error is reported from the CHIPs to RAID Manager, and a log
(syslog) is generated from RAID Manager.
