NOTES
■ With this command, you can change the device type of a CPG from logical disks of one
device type to logical disks of another device type (device types are Fibre Channel (
FC),
Nearline (
NL), or Solid State Drive (SSD)). This implies that, within a CPG, one can have
logical disks of type
FC, type NL, and type SSD. However, this is only permitted so that, if a
user wants to change the type of a CPG from FC to NL or SSD, they can first change the new
logical disk creation characteristics using
setcpg and then use region moves to change the
device types of existing logical disks. For this same reason, users are permitted to add
logical disks of a different device type to a CPG.
■ The options -sdgs, -sdgl and -sdgw control the auto LD creation for the CPG’s snapshot
data regions. Auto LD creation occurs when the amount of free LD space falls below the
specified grow (enlarge) size setting options (
-sdgs, -sdgl).
■ If auto-grow is enabled, new LDs will be created automatically in addition to any LDs
specified with -sa or -sd options.
■ Enter "" after the <pattern> option to remove the pattern.
■ Use movetodomain command to move a CPG from one domain to another.
