17 .sp
18 .LP
19 The \fBdsstat\fR command collects and reports I/O statistics for the Sun
20 StorageTek Availability Suite products.
21 .SH OPTIONS
22 .sp
23 .LP
24 The \fBdsstat\fR supports the following options:

26 .ne 2
27 .na
28 \fB\fB-m\fR \fB\fImode\fR\fR\fR
29 .ad
30 .sp .6

60 Remote Mirror statistics
61 .RE
63 To display statistics for multiple services simultaneously, use the \fB-m\fR
64 switch to specify each of the modes required. For example:
65 .sp
66 .in +2
67 .nf
68 % \fBdsstat -m ii -m sndr\fR
69 % \fBdsstat -m ii -m sndr -m cache\fR
70 .fi
71 .in -2
72 .sp
74 To determine which statistics are being reported from which service, use the
75 \fIrole\fR field, described below. When cache statistics are requested as one
76 of the multiple services, the \fBrkps\fR and \fBwkps\fR statistics is further
77 divided into \fBcrkps\fR, \fBdrkps\fR, \fBcwkps\fR, and \fBdwkps\fR. If no
78 \fB-m\fR switch is specified, then \fBdsstat\fR displays default statistics for
79 all of the valid modes as described above. See "Field Descriptions," below for
80 descriptions of these fields.

400 primary volume to determine if they match. Additionally, an Remote Mirror
401 volume should be specified as \fI<host>\fR:\fI<volume>\fR where \fI<host>\fR is
402 the primary or secondary host and \fI<volume>\fR is the volume name by which
403 that host recognizes the volume set. When specifying multiple Remote Mirror
404 volumes sets, be aware that each volume set specified is evaluated
405 individually, using the rules above. When displaying Point-in-Time Copy
