4.11.2 Raidar Command

The raidar command displays configuration, status, and I/O activity information for the
specified port/TID(s)/device(s) at the specified time interval. The configuration information
is acquired directly from the storage system (not from the configuration definition file).
Table 4.25 lists and describes the raidar command parameters. Figure 4.30 shows an
example of the raidar command and its output.
Note: The I/O activity of a TrueCopy S-VOL in the COPY or PAIR state includes TrueCopy
remote I/Os (update copy operations) in addition to host-requested I/Os. The I/O activity of
a ShadowImage S-VOL in the COPY or PAIR state includes only host-requested I/Os
(ShadowImage update copy operations are excluded). 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.

Value
raidar
raidar { -h ⎪ -q ⎪ -z ⎪ -p <port> <targ> <lun> ⎪ -pd[g] <raw_device ⎪ -s [interval] [count] }
-h: Displays Help/Usage and version information.
-q: Terminates the interactive mode and exits the command.
-z or -zx (OpenVMS cannot use the -zx option): Makes raidar command enter interactive mode. The -zx
option guards performing of the HORCM in the interactive mode. When this option detects a HORCM
shutdown, interactive mode terminates.
-I[H][M][instance#] or -I[TC][SI][instance#] Specifies the command as [HORC]/[HOMRCF], and used
for specifying instance# of HORCM.
-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-R and CL2-A to CL2-R (excluding CL1-I,
CL1-O, CL2-I, CL2-O).
For USP V/VM: CL3-a to CL3-r, or CLG-a to CLG-r for the expanded port.
For TagmaStore USP V/VM: CL3-a to CL3-r, or CLG-a to CLG-r for the expanded port.
For TagmaStore NSC: CL3-a to CL3-h, or CL8-a to CL8-h for the expanded port.
For 9900V: CL3-a to CL3-r, or CL4-a to CL4-r for the expanded port.
The port is not case sensitive (e.g. CL1-A= cl1-a= CL1-a= cl1-A, CL3-a= CL3-A= cl3-a= cl3-A).
<targ>: Specifies the SCSI TID (0 to 15) of the specified port (see Appendix C for fibre address
conversion information).
<lun>: Specifies the LUN (0 to 7) on the specified TID.
[mun]: Specifies the MU number of the specified LUN (ShadowImage only).
-pd[g] <raw_device>: Allows designation of an LDEV by raw device file name.
-pdg option is used to show a LUN on the host view by finding a host group (9900V and later).
-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 not specified, the default interval (3) is used.
[count]: Designates number of repeats. When omitted, this command repeats until CNTL-C.
