Workflow for maintaining the system

Maintenance of your HP XP7 storage system is performed by your HP Support Representative. In
most cases, issues in the array will be detected and reported to HP support automatically. However,
in the event you discover something, you may contact HP Support directly. See "Contacting HP"
in the "Support and other resources" section of this document.

Information about system and device maintenance

The following maintenance activities do not affect BC Z replication pairs.
Cache maintenance can reduce overall performance and should be scheduled during times
of low system activity.
Performing maintenance of physical disk drives that provision LDEVs used by BC Z can be
performed without impacting BC Z.
If a physical device failure occurs, the pair status is not affected because of the RAID
architecture.
If a physical device failure requires the HP XP7 storage system to utilize dynamic sparing or
automatic correction copy, the pair status is not be affected.
If an LDEV failure occurs, the HP XP7 storage system suspends the pair.
If a BC Z pair is using an LDEV, certain activities are not allowed. You can only block (for
maintenance), format, or restore an LDEV that is in use by only a pair in Suspend/SUSPER
status.
