Data Integrity Check and RAID Manager

Data Integrity Check is conﬁgured and operated using Data Integrity Check commands in R A ID Manager

XP. For RAI D Manager operations, refer to the HP StorageWorks RA I D 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 Integ rity Check.

NOTE:

The check is not started when the data is read.

When invalid data is detected, the error is reported from the CH IPs to RA I D Manager, and a log (syslog)

is generated from RAID M anager.
