Parity Recalculate
Click the right mouse button on the array drive icon.
A parity recalculate can be used to repair parity errors which have been previously detected with
the parity verify command logical_pverify. A parity recalculation initiates the same process used
for a build on an array drive. The user data on the drives is read, parity information is calculated
from this user data and the parity information is written anew.
While the parity recalculate is in progress the array is in the build state state_build. During this
time the array drive is not redundant. You can view the progress of the build process by clicking
the right mouse button on the array drive icon and selecting progress information
logical_progress_info.
After the parity recalculate is completed the array drive’s state changes again into ready with the
addition of /patch. This notification has no relevance to the operation of the array drive but is a
reminder that the parity information of the array drive has been recalculated once.
Progress Information
Click the right mouse button on the array drive or physical drive icons.
The progress information window shows the progress (elapsed time, estimated time, and percentage
of completion) of a parity verify logical_pverify, a disk array build state_build, or a surface check
pdisk_check. During an array drive rebuild, the information (user data and/or parity) of a specific
logical drive is calculated from the user data and parity information of the other logical drives and
written to this new logical drive. During a build of an array drive parity information is calculated
and written to a specific logical drive (RAID 1/4) or striped over the array drive (RAID 5).
