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. • tp_bzero. This indicates 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. • no_tp_zero. This indicates that the zero-fill operation is bypassed on the allocation of partially written data pages. • 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 , , , and , 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. showvv 517
