any deleted volumes or snapshots. The current allocation page size is 16kb. This is
the default setting.
no_tp_bzero
Using this option bypasses the zero-fill stage on the allocation of partially written
data pages. This is a performance improvement setting for thin provisioned
volumes.
The following options can be used when creating thinly provisioned virtual volumes (TPVVs):
-tpvv
Specifies that the created volume is a TPVV.
-usr_aw <percent>
Indicates a user space allocation warning. Generates a warning alert when the user data
space of the TPVV exceeds the specified percentage of the virtual volume size.
-usr_al <percent>
Indicates the user space allocation limit. The user space of the TPVV is prevented from
growing beyond the indicated percentage of the virtual volume size. After this limit is
reached, any new writes to the virtual volume will fail.
The following options can be used when creating fully provisioned volumes:
-snp_cpg <snap_cpg>
The name of the CPG from which the snapshot space is allocated.
-snp_aw <percent>
Provides a snapshot space allocation warning. Generates a warning alert when the
snapshot space of the virtual volume exceeds the specified percentage of the virtual
volume size.
-snp_al <percent>
Provides a snapshot space allocation limit. The snapshot space of the virtual volume is
prevented from growing beyond the indicated percentage of the virtual volume size. After
being reached, new writes to the virtual volume will fail.
SPECIFIERS
<usr_CPG>
Specifies the name of the common provisioning group (CPG) from which the volume user
space will be allocated. If the
-tpvv option is specified, the volume is thinly provisioned.
