7.10.3 Modifying a Common Provisioning Group
You can modify CPGs in several ways. The following modifications are commonly performed on
CPGs using variations of the
setcpg command and are described in the sections that follow:
 Specify the percentage of used snapshot administration space or snapshot data space that
will generate an alert.
 Specify the amount of logical disk storage space created on each auto-grow operation.
For more details on additional ways a CPG can be modified using the
setcpg command, see
the InForm OS Command Line Interface Reference.
7.10.3.1 Setting Snapshot Space Usage Warnings
X To set or modify the space usage warning for a CPG, issue the setcpg -sdgw <size>
<CPG_name>
command, where:
 -sdgw <size> is the space limit for logical disk space before a warning alert is
generated. If 0 (default) is specified, no warning limit it enforced.
 <CPG_name> is the name of the CPG being created.
7.10.3.2 Setting a Common Provisioning Group’s Autogrow Size
X To set or modify a CPG’s autogrow size, issue the setcpg -sdgs <size> <CPG_name>
command, where:
 -sdgs <size> is the amount of logical disk storage created during each autogrow
operation. Refer to Table 7-1 on page 7.11 for the minimum default growth sizes per
number of nodes.
 <CPG_name> is the name of the CPG being created.
NOTE: Before modifying your CPG’s autogrow settings see 7.10.1 Growth
Increment Considerations on page 7.11 for guidelines.
