this is what in my system
1. production server
-hdisk0(rootvg)
-hdisk1(rootvg) (mirrored)
-hdisk2(datavg)
-hdisk3(datavg)
PP SIZE for these two VG is 256MB
2. DR server
-hdisk0 ( prepare for restore unmirrored rootvg)
-hdisk1 ( prepare for datavg)
When setting SAN storage i have defined 128MB as PP SIZE for hdisk0 and hdisk1
My solution is like this:
1.back up mirrored hdisk0 hdisk1 with mksysb in (tape no.1)
2.back up datavg hdisk2 hdisk3 ( tape no.2 for DR server hdisk1)
--break mirror/unmirror hdisk1--
3.back up unmirrored hdisk0 only( tape no.3 for DR server hdisk0 used)
question: would it influence DR server hdisk0 and hdisk1 since PP SIZE is 128MB but backup from production server is 256MB.

I backed up a unix database using
"tar -cvf /dev/rmt1 -N 800 /*"
Normally I would restore this using
"tar -xvf /dev/rmt1 -N 800"
This is reporting an error about
"not enough memory"
I have done a new test backup and restore using the same commands and they work.
ANY IDEAS ? (2 Replies)

dmxgetscreencount
DMXGetScreenCount(3) Library Functions Manual DMXGetScreenCount(3)
NAME
DMXGetScreenCount - determine number of back-end screens
SYNOPSIS
#include <X11/extensions/dmxext.h>
Bool DMXGetScreenCount(Display *dpy,
int *screen_count);
DESCRIPTION
DMXGetScreenCount() returns the number of back-end screens that a Xdmx(1) server controls. Since a DMX screen usually fills all of the
available area on a back-end server, there is usually a one-to-one correspondence between DMX screens and backend servers. However, it is
also possible for a DMX screen to cover only part of the available area on a back-end server, and for more than one DMX screens to occupy
different parts of the visible area on the same back-end server.
A DMX screen may be managed as a regular X screen in the Xdmx(1) server or may be joined with other DMX screens using Xinerama.
RETURN VALUE
DMXGetScreenCount() sets screen_count and returns True unless there is a protocol error.
NOTES
If Xinerama is active, only one logical screen will be available to clients of the Xdmx(1) server. However, this call will accurately
reflect the number of composite back-end screens that the Xdmx(1) server is using.
