HP XP RAID Manager Software - Manual (Page 45)

The masking feature is to enable the tracing without changing their scripts. And this feature
is available for all RAID Manager commands (except inqraid or EX_xxx error code).
For example, if you want to mask pairvolchk (returns 22) and raidqry, specify the following:
pairvolchk=22 raidqry=0
You can track script performance, and then decide to mask by auditing the command logging
file, as needed.
