Temporarily Stopping a Revive Operation
If you have enabled automatic sector reallocation, the system spares the sector
and the revive operation resumes. If automatic sector reallocation is disabled, see
Temporarily Stopping a Revive Operation on page 7-8.
•
Nonfatal checksum errors have stalled a revive operation or put it into a loop.
Symptoms are:
°
The revive interval in a STATUS, DETAIL display has become large.
°
The Current Logical Sector remains unchanged.
°
EMS messages are generated. Research these messages with the Event
Management Service (EMS) Analyzer User’s Guide and Reference Manual.
The revive operation continues to retry at the current address until it is successful,
suspended, or stopped.
After each retry, the revive interval doubles in length. In this way, the retries do not
consume system resources or produce too many operator messages. The interval
continues to double up to a maximum of one hour; thereafter retries occur
indefinitely. If a retry succeeds, the revive interval returns to its original configured
value.
See Temporarily Stopping a Revive Operation on page 7-8.
Temporarily Stopping a Revive Operation
1. Temporarily stop the disk being revived:
-> RESET $DATA01-M
The disk remains in the STARTING state, REVIVE substate.
2. While the revive operation is suspended, do what needs to be done to resolve the
problem. For example, spare the defective sector.
3. Resume the revive operation:
-> START $DATA01-M
The revive operation resumes from the point at which it was stopped.
