Raidar command
The raidar command displays configuration, status, and I/O activity
information for the specified array port, TIDs, and devices at the specified
time interval. The configuration information is acquired directly from the
array (not from the configuration definition file). Table 1-19 lists and
describes the raidar command parameters. Figure 1-45 shows an example
of the raidar command and its output.
•
NOTE:
• The I/O activity of a ShadowImage or SnapShot S-VOL in the COPY or PAIR state
includes only host-requested I/Os. The I/O activity of a P-VOL or simplex volume
includes only host-requested I/Os. If state changed into SMPL in S-VOL (COPY, PAIR)

I/O actively, and then I/O activity of the between is reported in the SMPL state.
•
The array has I/O activity information to be displayed for each controller.
Therefore, if you want to display the I/O information using this command, when
creating the configuration definition file, you must set the command device that is
specified by the controller that accepts the host I/O

Parameter Value
Command
Name raidar
Format raidar { -h  -q  -z  -I[H  M][instance#]  -p <port> <targ> <lun> <mun>
 -pd[g]  raw_device  -s [interval] [count] }
Options -h: Displays help, usage, and version information.
-q: Terminates the interactive mode and exits the command.
-z or -zx: Makes the raidar command enter the interactive mode. The -zx
option guards performing of the HORCM in the interactive mode. When this
option detects a HORCM shut down, interactive mode terminates.
-I[H | M][instance#] or -I[TC | SI][instance#]: Specifies the instance
number and the command execution environment. Refer to section
Instance
number and option for command execution environment on page 1-4 .
-p <port> <targ> <lun> <mun>....: Monitors one or more (up to 16)
devices at a time. 
<port>: Specifies the port to be reported: CL1-A to CL1-D 
and CL2-A to CL2-D. This option must be specified. 
<targ>: Specifies the SCSI or Fibre target ID (0 to 15) of the specified
port. 
<lun>: Specifies the LUN (0 to 7) on the specified TID. 
<mun>: Specifies the MU number of the specified LUN.
Pd[g] <raw_device>: Allows designation of an LDEV by raw device file
name. -pdg option is specified to find host group and to display LUN.
-s [interval]
or -sm [interval]: Designates the time interval in seconds.
-s: Interprets the time interval as seconds.
-sm: Interprets the time interval as minutes.
[ interval]: Designates the time interval value (1 to 60). If the interval is not
specified, the default interval (3) is used.
[count]:
Designates number of repeats. When omitted, this command
repeats until Cntl-C.
