Hello
I am a noobie to HACMP
I have 2 55A servers and a 7031 disk subsystem
For HACMP to work, do I need to have the hdisks on both servers to match the same drives??

kstat
kstat(1M) System Administration Commands kstat(1M)
NAME
kstat - display kernel statistics
SYNOPSIS
kstat [-lpq] [-T u | d ] [-c class] [-m module] [-i instance] [-n name] [-s statistic] [interval [count]]
kstat [-lpq] [-T u | d ] [-c class] [module:instance:name:statistic...] [interval [count]]
DESCRIPTION
The kstat utility examines the available kernel statistics, or kstats, on the system and reports those statistics which match the criteria
specified on the command line. Each matching statistic is printed with its module, instance, and name fields, as well as its actual value.
Kernel statistics may be published by various kernel subsystems, such as drivers or loadable modules; each kstat has a module field that
denotes its publisher. Since each module may have countable entities (such as multiple disks associated with the sd(7D) driver) for which
it wishes to report statistics, the kstat also has an instance field to index the statistics for each entity; kstat instances are numbered
starting from zero. Finally, the kstat is given a name unique within its module.
Each kstat may be a special kstat type, an array of name-value pairs, or raw data. In the name-value case, each reported value is given a
label, which we refer to as the statistic. Known raw and special kstats are given statistic labels for each of their values by kstat; thus,
all published values can be referenced as module:instance:name:statistic.
When invoked without any module operands or options, kstat will match all defined statistics on the system. Example invocations are pro-
vided below. All times are displayed as fractional seconds since system boot.
OPTIONS
The tests specified by the following options are logically ANDed, and all matching kstats will be selected. A regular expression containing
shell metacharacters must be protected from the shell by enclosing it with the appropriate quotes.
The argument for the -c, -i, -m, -n, and -s options may be specified as a shell glob pattern, or a Perl regular expression enclosed in '/'
characters.
-c class Displays only kstats that match the specified class. class is a kernel-defined string which classifies the "type" of the
kstat.
-i instance Displays only kstats that match the specified instance.
-l Lists matching kstat names without displaying values.
-m module Displays only kstats that match the specified module.
-n name Displays only kstats that match the specified name.
-p Displays output in parseable format. All example output in this document is given in this format. If this option is not
specified, kstat produces output in a human-readable, table format.
-q Displays no output, but return appropriate exit status for matches against given criteria.
-s statistic Displays only kstats that match the specified statistic.
-T d | u Displays a time stamp before each statistics block, either in ctime(3C) format ('d') or as an alphanumeric representation
of the value returned by time(2) ('u').
OPERANDS
The following operands are supported:
module:instance:name:statistic Alternate method of specifying module, instance, name, and statistic as described above. Each of the mod-
ule, instance, name, or statistic specifiers may be a shell glob pattern or a Perl regular expression
enclosed by '/' characters. It is possible to use both specifier types within a single operand. Leaving a
specifier empty is equivalent to using the '*' glob pattern for that specifier.
interval The number of seconds between reports.
count The number of reports to be printed.
EXAMPLES
In the following examples, all the command lines in a block produce the same output, as shown immediately below. The exact statistics and
values will of course vary from machine to machine.
Example 1: Using the kstat Command
example$ kstat -p -m unix -i 0 -n system_misc -s 'avenrun*'
example$ kstat -p -s 'avenrun*'
example$ kstat -p 'unix:0:system_misc:avenrun*'
