Adtron I35MB Operations Manual

Rebuilding a bank

After a bank has been replaced, a rebuild must be performed. To start a Bank Rebuild, press the mirror control button between 5 and 10 seconds on the off-line bank. Release the button when the Access LED starts flashing at 2 blinks per second. The rebuild process begins, indicated by the Access LED turning solid green and the Fault LED flashing green. When complete, the Fault LED changes from flashing green to off. It is faster to do the rebuild when there is no host activity to the I35MB.

A rebuild operation copies the contents of the entire media at a rate of roughly 5 MB/sec, requiring several hours for large capacities. Depending on concurrent host activity, the rebuild process may be slowed. The higher the level of concurrent host activity, the more the rebuild process may be impacted (slowed).

Rebuilding a Bank Off-line

Only the power connection is required to do the rebuild if you want to have a rebuild complete before bringing the drive on line. No host activity interruption results in the fastest rebuild time.

Using Different Size Media

The I35MB can support different size drives in each bank and still operate the mirroring function. The rules for this operation are as follows:

Media inserted to replace the factory original must have a capacity that is equal to or greater than the original media size.

The capacity of the mirrored unit remains the same size as when shipped from the factory. In other words, if the drive shipped from the factory with a capacity of 20GB, it will retain that capacity regardless of the actual capacity of the media in either bank.

Any media inserted into a bank that is smaller than the original capacity can not be used for mirroring. Rebuild attempts to a smaller media will not start. The LEDs will indicate a mirror fault condition.
