Server Class DEFINEs
You can specify the default volume and subvolume for a server class using the
VOLUME attribute of the SET SERVER command or the VOLUME attribute of
_DEFAULTS DEFINE. If you do not specify _DEFAULTS DEFINE, the PATHMON
process uses the volume and subvolume you assigned with the VOLUME attribute. If
you assign _DEFAULTS DEFINE and a VOLUME attribute, the PATHMON process
ensures that these values correspond. If you add or replace _DEFAULTS DEFINE, the
VOLUME value changes. Similarly, altering the value of the VOLUME attribute
changes the VOLUME attribute of _DEFAULTS DEFINE.
For more information about DEFINEs and using _DEFAULTS DEFINE, see the TACL
Reference Manual and the Guardian User’s Guide.
Considerations
•
If you repeat a SET SERVER command with a different attribute value, the
PATHMON process uses the last value entered for the server class attribute.
•
All attributes defined for a server class must be consistent with the value defined
for PROCESSTYPE. Inconsistent attributes are rejected with error 2066 or error
2067. To reduce possible confusion, HP recommends that you configure the
PROCESSTYPE attribute first.
•
The CMDCWD and the SET SERVER CWD commands both define a value for the
CWD attribute. They do not function the same way, however.
When resolving relative OSS pathnames, the value defined by the SET SERVER
CWD command takes precedence. The RESET SERVER command resets this
value to null.
The value defined by the CMDCWD command is used to resolve relative OSS
pathnames only if no value has been set using the SET SERVER CWD command.
It is a default absolute pathname that you can define for a server class. The
RESET SERVER command has no effect on this value. To reset this value to null,
use the RESET CMDCWD command.
•
A running server process that is stopped and restarted does not reuse the
processor of the stopped server process. The restarted process uses the next
processor specified in the cyclical list of CPUs.
If you alter a server process, that process uses the first processor in the cyclical list
of CPUs when it is restarted. If the server class is stopped and restarted, it does
not reuse the processor of the stopped server class. The restarted server class
uses the next processor in the cyclical list of CPUs.
•
If you specify a value for the TIMEOUT attribute and an I/O to a server process
times out because of the TIMEOUT value, the link management process cancels
the I/O to the server and returns the link. If the link was the last link to the server,
the server stops.
