ENV Command
•
Deleting a file on a down disk
If you attempt to delete a configured swap file on a disk that is down, KMSF marks
the file for deletion in the ZSYSCFG file. Once the disk comes up, KMSF attempts
to delete the swap file as it would normally do.
ENV Command
The ENV command displays various environmental information for NSKCOM,
including:
•
The NSKCOM version
•
Currently assumed swap file attributes
•
Current and default subvolume names
•
Whether logging is enabled and the LOG file name, if any
•
Processor page size (the number of bytes per memory page)
•
All swap files known to NSKCOM, including both configured and default swap files
•
Indicators of pending DELETE commands, pending STOP commands, and non-
default THRESHOLD values for all swap files that have them
The ENV command does not display the status of swap files. To find out if a swap file
is in use or not, use the INFO or STATUS command.)
