When the used capacity of a pool that provisions a TSE-VOL or ESE-VOL exceeds the user-defined threshold value, a warning message is issued to the host.
The following shows examples of warning messages for a pool that provisions a TSE-VOL (and that does not provision an ESE-VOL). For details about a pool that provisions an ESE-VOL, see the description of threshold value in the Provisioning Guide for Mainframe.
- If the user sets the warning threshold to 70%, and the pool usage capacity exceeds this threshold, the following warning message is issued:
REPOSITORY VOLUME WARNING: AT 30% CAPACITY REMAINING
- If the user sets the depletion threshold
to 80%, and the pool usage capacity exceeds this threshold, the following warning
message is issued:
REPOSITORY VOLUME WARNING: AT 20% CAPACITY REMAINING
- If the pool usage rate reaches 100%, the following warning message is issued:
REPOSITORY VOLUME EXHAUSTED
The above messages are issued when the threshold is reached regardless of the number of FlashCopy® SE relationships that exist when an I/O operation is performed to a single TSE-VOL.
Messages are reported to all hosts that have one of the volumes online that is running out of space. If a host has more than one of these volumes online, only one of the volumes is mentioned in the message.
- TSE-VOL (FlashCopy® SE target volume or volume in Simplex status) or ESE-VOL associated with the pool
- Source volume in a FlashCopy® SE relationship
