_a_s_c_h_e_c_k validates the configuration on all the array services daemons
known to the local array services daemon. Checks are made to ensure that
the various array and machine definitions are consistent with each other,
both on the individual servers and with corresponding definitions on the
other servers. If any problems are found, they are described in detail
and suggestions are provided to correct the situation.
It should be noted that _a_s_c_h_e_c_k is not a syntax checker for the
individual array services configuration files; that function is handled
by the ----cccc option of _a_r_r_a_y_d(1M). Instead, _a_s_c_h_e_c_k is used to check the
semantics of a syntactically correct array services configuration file.
_a_s_c_h_e_c_k relies on information provided by array services. Thus, for
complete coverage, an array services daemon should be running on every
machine that is mentioned in the local configuration file(s).
The checks that _a_s_c_h_e_c_k makes include:
* Ensuring that the local array services daemon is accessible.
* Verifying that all of the array services daemons known to the local
daemon are also available.
* Ensuring that each array services daemon is using the correct version
of the array services library.
* Ensuring that the LOCAL IDENT value used by a particular array
services daemon is not different from the "machine ID" used by the OS
on that daemon's machine.
* Suggesting that a "machine ID" be set in the OS on those systems that
have an array services daemon but have not yet set a machine ID.
* Ensuring that no two arrays on a particular server have the same ARRAY
IDENT value.
* Ensuring that the SERVER IDENT value which may be declared for a
particular ARRAY/MACHINE definition matches the LOCAL IDENT value of
the corresponding server.
* Warning if the list of machines defined for a particular array does
not match the list of machines for an array with the same name on a
different server.

* Warning about any server that has two or more arrays defined but has
not specified a default array.

_a_s_c_h_e_c_k takes several options, primarily to control the selection of the
"local" server, and to select the desired amount of output. The valid
options include:
----DDDD When used with ----ssss, indicates that array services requests
should sent directly to the specified server, rather than
being forwarded to that server by the array services daemon
running on the current machine. This is the default
behavior.
----FFFF When used with ----ssss, indicates that array services requests
should be forwarded to the specified server via the server on
the current machine rather than sent directly.
----KKKKllll _k_e_y Use _k_e_y for the local authentication key when communicating
directly with a remote array services daemon.
----KKKKrrrr _k_e_y Use _k_e_y for the remote authentication key when communicating
directly with a remote array services daemon.
----pppp _p_o_r_t Specifies the port address of the "local" _a_r_r_a_y_d server.
Defaults to the value of the AAAARRRRRRRRAAAAYYYYDDDD____PPPPOOOORRRRTTTT environment variable
if present, or 5434 otherwise.
----qqqq Produce less verbose ("quieter") output. Repeated
occurrences (either ----qqqq ----qqqq ............ or ----qqqqqqqq ............) may decrease the
verbosity further.
----ssss _s_e_r_v_e_r Specifies the hostname or IP address of the "local" _a_r_r_a_y_d
server. Defaults to the value of the AAAARRRRRRRRAAAAYYYYDDDD environment
variable if present, or "localhost" otherwise.
----tttt _v_a_l_u_e Specifies the timeout value (in seconds) used for waiting on
individual responses from the array daemon.
NNNNOOOOTTTTEEEESSSS
The array services daemon (_a_r_r_a_y_d(1M)) must be running on all machines
that are to be examined. It does not necessarily have to be running on
the machine that executes _a_s_c_h_e_c_k if an alternate server was specified in
some way.
