Enabling Database Validator Checking; Enabling Database Validator Checking With Lvm Considerations - HP StorageWorks P9000 User Manual

Enabling Database Validator checking

The following example shows the RAID Manager raidvchkset commands used to enable
Database Validator for the sample configuration shown in
Parameters with g specify the group of LDEVs with group name written in horcm.conf.
Parameters with vt specify the validation file type described in
Parameters with vs specify the Oracle data block size in units of 512 bytes. For example,
16 means 8KB.
IMPORTANT:
checking with LVM considerations.

Enabling Database Validator checking with LVM considerations

LVM may write metadata to the volume depending on the volume configuration. In this case, you
must exclude the metadata area from the validation target range. You can specify the target range
for each volume with the extended parameters of the raidvchkset
StorageWorks P9000 RAID Manager Reference Guide for the exact syntax. The vxdisk list
and vxdg list commands show the range of metadata regions for the VxVM LVM, which are
called private regions. See the VxVM documentation for information on private regions.
The following is an example of using the VxVM vxdisk list command to determine the target
range and the correct syntax for excluding the metadata from the validation target range.
Specifically, this example is for the Redo log.
