InForm OS Version 2.2.4 Command Line Interface Reference
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 to ensure 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.
Multiple policies can be specified and are separated with commas. If a policy is not
specified, the policy defaults to
stale_ss.
The following options can only be used on thinly provisioned virtual volumes:
-usr_aw <percent>
This option returns a user space allocation warning. It generates a warning alert when the
user space of the TPVV exceeds the specified percentage of the virtual volume size.
-usr_al <percent>
This option returns 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 size is
reached, any new writes to the virtual volume will fail.
The following options can only be used on fully provisioned volumes:
-usr_cpg <user_CPG>
Specifies that the volume user space that is to be provisioned from the specified CPG. This
option moves all the logical disks currently contained in the user space for these volumes
into the CPG. This is permitted only when none of the logical disks are shared with other
volumes that are not specified with this option. If the
<usr_CPG> specifier is specified as
"", the volume user space is no longer provisioned from a CPG and the existing user space
logical disks will be removed from the CPG. This is permitted only when the existing user’s
logical disks are exclusively being used by the volumes specified with this option.
