Another case of SVOL-takeover
An SVOL-takeover from Host B to Host D will do nothing because the
S-VOL was already in SSWS state.
S-VOL data consistency function
The consistency of the data within a pair is determined by the pair status
and the fence level of the pair. The paircurchk command can be specified
for each paired logical volume or each group. If this command is specified
for a group, a data consistency check runs for all volumes in the group.
Inconsistent volumes are printed in the message log and displayed.
See the table on the next page for details on this function. The terms used
