HP 3PAR OS 3.1.3 Command Line Interface Reference

The following example shows the policies associated with a volume:
cli% showvv -pol
Id Name --------------------------Policies--------------------------
0 admin stale_ss,system,no_zero_detect
19 aldvv stale_ss,no_system,no_one_host,no_zero_detect
20 bar-remote stale_ss,no_system,no_one_host,no_cache,no_zero_detect
11 mytpvv stale_ss,no_system,no_one_host,no_zero_detect
6 rcopy.0 stale_ss,no_system,no_one_host,no_zero_detect
7 rcopy.1 stale_ss,no_system,no_one_host,no_zero_detect
21 s026-foo stale_ss,no_system,no_one_host,no_cache,no_zero_detect
18 testgrow stale_ss,no_system,no_one_host,no_zero_detect
12 tpvv stale_ss,no_system,no_one_host,no_zero_detect
13 vv.0 stale_ss,no_system,no_one_host,no_zero_detect
14 vv.1 stale_ss,no_system,no_one_host,no_zero_detect
15 vv.2 stale_ss,no_system,no_one_host,no_zero_detect
16 vv.3 stale_ss,no_system,no_one_host,no_zero_detect
17 vv.4 stale_ss,no_system,no_one_host,no_zero_detect
The columns in the previous example are identified as follows:
• stale_ss. Stale snapshots. If there is no space for a copy-on-write operation, the snapshot
is allowed to go stale but the host write can proceed without an error.
• no_stale_ss. No stale snapshots. If there is no space for a copy-on-write operation, the
host write will fail.
• one_host. This indicates a volume is constrained to export to one host or one host cluster.
• no_one_host. This indicates a volume exported to multiple hosts for use by a cluster-aware
application, or when "port presents" VLUNs are used.
• zero_detect. This indicates that the HP 3PAR storage system will scan for zeros in the
incoming write data.
• no_zero_detect. This indicates that the HP 3PAR storage system will not scan for zeros in
the incoming write data.
• no_cache. This indicates that the HP 3PAR storage system is disabled for write caching, read
caching, and read ahead for the volume. This is a read-only policy and cannot be set.
NOTES
• The per-snapshot space is approximate and must be calculated using the updatesnapspace
command.
• If the -showcols option is used, the full column names are shown in the header otherwise
the header contains abbreviated column names.
• For <cpgname_or_pattern>, <hostname_or_pattern>, <groupname_or_pattern>,
and <domainname_or_pattern>, the patterns are glob-style (shell-style) patterns. Refer to
“Glob-Style Pattern” (page 12) for further information.
• A Domain column may be included by using the setclienv command to set listdom to
1. The listdom option is also set to 1 if the CLI was started with the -listdom option, or
if the CLI was started with the TPDLISTDOM environment variable set. Please run cli -h
and setclienv -h for details of the environment variables.
• The showvv command has new properties that provide statistics on the growth and reclamation
of usr, snp, and adm space within a volume. These properties can be displayed using the
-showcols option. The new properties, as shown by the -listcols option are
Grown_Adm_MB, Grown_Snp_MB, Grown_Snp_SD_MB, Reclaimed_Adm_MB,
Reclaimed_Snp_MB, or Reclaimed_Snp_SD_MB. These statistics are only available via
the CLI and only via the -showcols option.
