Storage Controller Features 39
•
Patrol Read
adjusts the amount of controller resources dedicated to
Patrol Read
operations based on outstanding disk I/O. For example,
if the system is busy processing I/O operation, then
Patrol Read
uses
fewer resources to allow the I/O to take a higher priority.
•
Patrol Read
does not run on any disks involved in any of the
following operations:
–Rebuild
– Replace Member
– Full or Background Initialization
–CC
–RLM or OCE
NOTE: By default, Patrol Read automatically runs every seven days on configured
SAS and SATA hard drives. Patrol Read is not necessary on SSD and is disabled by
default.
