Note: When disk space is low, click the Quick Warning icon [!]

Note: When disk space is low, target replication to the system is
paused (see Replication Service on page 161). In addition,
space reclamation is automatically started to free up disk
space (see Space Reclamation on page 371).
Note: For optimal system performance, Quantum recommends
keeping the amount of Available Disk Space (free space)
at 20% or more.
