About Operating Pools and TSE-VOLS
Operating when Pool is full
The usage amount in a pool is controlled in units of pages along with Thin Provisioning Z, and the
usage amount for TSE-VOL is controlled in units of track in that page. Even if a pool becomes full,
the data that is updated in the S-VOL can be successfully copied to T-VOL if THP Z pages that are
allocated to that TSE-VOL have space.
When the accessed location is unallocated and the T-VOL page has no space, usually read and
write processing cannot be performed. However, if the location has been already allocated, read
processing can be performed. When performing an update operation with the S-VOL in a state of
no space in allocated pages, the copying of corresponding data to the T-VOL fails and the
relationship will enter the Failed State, making the read and write operations for T-VOL to be not
available. To restore from the Failed State, the relationship must be released.
