Table 5. Set CC input options
Option Value range Description
cc
seq: Sequential mode.
conc: Concurrent mode.
off: Turns off the consistency check.
Sets CC to either sequential mode, or concurrent
mode, or turns off the CC.
NOTE: The concurrent mode slows I/O
processing.
delay
-1 and any integer value. Delay a scheduled consistency check. The value
is in hours. A value of 0 makes the CC runs
continuously with no delay (in a loop).
NOTE: Only scheduled consistency checks
can be delayed.
starttime
A valid date and hour in 24-hours format. Start time of a consistency check is yyyy/mm/dd
hh format.
excludevd
The range should be less than the number of
virtual drives.
Excludes virtual drives from the consistency
checks. To exclude particular virtual drives, you
can provide list of virtual drive names (Vx,Vy …
format) or the range of virtual drives that you
want to exclude from a consistency check (Vx-
Vy format). If this option is not specified in the
command, no virtual drives are excluded.
none
Virtual drives if any were excluded before, will be
removed.
Input example:
perccli /c0 set CC=on starttime=2012/02/21 00 excludevd v0-v3
perccli /cx show cc
This command shows the consistency check schedule properties for a controller.
Input example:
perccli /c0 show cc
perccli /cx show ccrate
This command checks the status of a consistency check operation. The CC rate appears in percentage.
Input example:
perccli /c0 show ccrate
NOTE: A high CC rate slows I/O processing.
Controller security commands
The PERC Command Line Tool supports the following controller security commands:
perccli /cx compare securitykey=xxxxxxxxxx
perccli /cx delete securitykey
perccli /cx set securitykey keyid=xxx
perccli /cx set perccli/cx securitykey=xxxxxxxx keyid=xxx
perccli /cx set securitykey=xxxxxxxx oldsecuritykey=xxxxxxxx [keyid=xxx]
The detailed description for each command follows.
