Porting notice for MPE/iX

Introduction

MPE/iX does not fully support POSIX like UNIX. Therefore, RAID
Manager has some restrictions in MPE/iX. The system calls (wait3(),
gettimeofday()... ) that are not supported on MPE/iX are implemented in
LIB BSD; however, RM has to avoid using LIB BSD due to its availability
as free software. These functions are, therefore, implemented within RM.
RM has accomplished porting within standard POSIX for MPE/iX only.

Restrictions in the current release

RAID Manager has the following restrictions in porting to MPEiX.

Network function

The Bind() system call of MPE/iX POSIX cannot specify the Ip_address of
its own host, so it supports only ‘INADDR_ANY’. Therefore, RAID
Manager needs to use ‘NONE’ like the following on the horcm.conf. Also
a port number over 1024 must be specified in ‘/etc/services’.

Syslog function

RAID Manager does not support the syslog function of MPE/iX due to free
software availability. Also, the syslog daemon (syslogd) does not execute at
normal startup on MPE/iX. As an alternative, the HORCM daemon uses a
logging file.
