Regex Tester & Validator

This PCRE regular expression is designed to parse a single line of output from an HP 3PAR storage array's `showvv` command. It utilizes named capture groups to extract specific details about a thin-provisioned virtual volume, including its ID, name, read/write status, and various space utilization metrics. The pattern strictly matches base volumes that are thin provisioned (tpvv), have no copy ("---"), and are currently in a normal or degraded state.
