Scrubbing a Mirror Set
The CLI allows you to scrub a mirror set. Scrubbing a mirror set
reconstructs the data on both mirror halves (partitions), if they are
found to be different. You use the
container scrub command to
scrub a mirror set.
To work with mirror set scrubbing, you must understand:
■ The mirror set scrubbing attributes that you can specify
■ How to scrub a mirror set
The following sections discuss each of these topics.
Understanding the Mirror Set Scrubbing Attributes You can Specify
You use the container scrub command to scrub a mirror set.
Before scrubbing a mirror set, consider the following attributes you
can specify:
■ I/O delay
■ No repair
■ Wait
Specifying the I/O Delay When Scrubbing a Mirror Set
The i/o delay attribute indicates the number of milliseconds the
controller waits between the I/O operations required to scrub the
redundant container. The I/O delay value is not preserved between
operating system reboots. Valid values are 0 through 100.
In the following example, the container scrub command with
the /io_delay switch sets the delay to 10 milliseconds.
HPN0> container scrub /io_delay=10 2
Executing: container scrub /io_delay=10 2
Specifying No Repair when Scrubbing a Mirror Set
The no repair attribute indicates if the scrub operation repairs
errors if they are encountered.
In the following example, the container scrub command with
the /no_repair switch repairs errors if they are encountered.
HPN0> container scrub /no_repair=FALSE 2
