SuperTrak EX Series User Manual
256
the bad sector remapping table, which has a capacity of 512 reassigned blocks
and 1024 error blocks.
When the table fills to a specified percentage of its capacity, PDM triggers a
migration of data from the suspect drive (the physical drive with the bad sectors)
to a spare drive.
During data migration, you will have access to the logical drive but it will respond
more slowly to read/write tasks because of the additional operation. The time
required for data migration depends on the size of the physical drive.
See “Making Background Activity Settings” on page 137.
Transition
The Transition feature enables you to specify “permanent” spare drives for your
SuperTrak controller. Transition is the process of replacing a revertible spare
drive that is currently part of a disk array with an unconfigured physical drive or a
non-revertible spare. The revertible spare drive returns to its original status.
Transition happens automatically when the following sequence of events takes
place:
• You create a revertible spare drive. “Creating a Spare Drive” on page 179.
• One of the physical drives assigned to your disk array fails and the array
becomes degraded and the logical drive goes critical.
• The SuperTrak controller automatically rebuilds your array to the revertible
spare drive and the array becomes functional again.
• You replace the failed physical drive with a new physical drive of equal or
greater capacity.
• The SuperTrak controller automatically transitions (moves) the data from the
revertible spare to the new physical drive.
• The new physical drive becomes part of the array and the revertible spare
drive returns to its original spare status.
Transition happens manually when you specify a different unconfigured physical
drive to transition (move) the data from the revertible spare drive.
Drive Failure and Automatic Rebuild
In the example below, there is a two-drive RAID 1 disk array.
• The physical drives in channels 1 and 2 belong to the disk array.
• The physical drive in channel 3 is unconfigured.
