InForm OS Version 2.3.1 Command Line Interface Reference
stale_ss
Specifies that invalid snapshot volumes are permitted. Failure to update snapshot
data does not affect the write to the base volume, but the snapshot is considered
invalid.
no_stale_ss
Specifies that invalid snapshot volumes are not permitted. Failure to update a
snapshot is considered a failure to write to the base volume.
one_host
This constrains the export of a volume to one host or one host cluster (when cluster
names can be used as a host name).
no_one_host
This policy should only be used when exporting a virtual volume to multiple hosts
for use by a cluster-aware application, or when “port presents” VLUNs are used. This
is the default policy setting.
tp_bzero
Specifies that if a host write results in the allocation of a new data page that is only
partially filled by the host write, then a zero-fill is performed on the unwritten
portion of the data page. This ensures that the host cannot read data from deleted
volumes or snapshot. The default allocation page size is 16 KB.
no_tp_bzero
Specifies that the zero-fill operation is bypassed on the allocation of partially
written data pages.
-usr_cpg <usr_cpg>
Specifies the name of the CPG from which the user space will be allocated.
-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.
