Logical devices are each assigned one of the statuses described in the following table:
Table 177 Logical Device Status
Status |
Description |
|---|---|
ACTIVE/BUSY |
The device is processing a request for file access. |
IDLE |
The device processed a request recently and is waiting for another request. |
INACTIVE |
The device is not processing any requests. |
When a logical device finishes processing a request, it checks the DSN queue for the next request. If no request is found, the logical device enters the IDLE status. If no request is detected within a limited time period, the device is assigned a status of INACTIVE.
If no requests are being processed and the number of usable devices is one or more, device number one retains a status of IDLE (that is, its status is not set to INACTIVE).
