Sun M5000 servers diaster recovery plan
Hi, We have two Sun M5000 systems. A is Oracle server and B is testing server. There are nine Solaris 10 zones set on A. SAN is connecting to A with ZFS configuration.

Now we want to set B to be a backup server of A and make the two as identical as possible. No VERITAS cluster, no Solaris cluster, and no Oracle RAC since we don't have the budget to pay more Oracle licenses.

Here is my plan:
(1) Set XSCF on B according to settings on A.
(2) Load Solaris 10 global zone on B.
(3) Backup Solaris 10 global zone on A, and restore the backup on B by using NetBackup.
(4) Copy local zones from A, and paste them to B.
(5) Set FC HBA on B and configure SAN zone to connect to B.
(6) Set ZFS on B according to A's ZFS.

How to solve IP conflict issue?
(1) Disconnect B from LAN.
(2) Transfer A's local zones to B under B console.
(3) Change IP addresses of local zones on B.

Is this plan workable? Any potential issues? Any suggestions? Please help.

Thank you in advance!

NAME

       zcons - Zone console device driver

DESCRIPTION

       The  zcons character driver exports the console for system zones. The driver is comprised of two "sides:" a master side with which applica-
       tions in the global zone communicate, and a slave side, which receives I/O from the master side. The slave side is available in the  global
       zones.

       Applications must not depend on the location of /dev or /devices entries exported by zcons. Inside a zone, the zcons slave  side is fronted
       by /dev/console and other console-related  symbolic links, which are used by applications that expect to write to the system console.

       The zcons driver is Sun Private, and may change in future releases.

FILES

       /dev/zcons/<zonename>/masterconsole

	   Global zone master side console for zone <zonename>.

       /dev/zcons/<zonename>/slaveconsole

	   Global zone slave side console for zone <zonename>.

       /dev/zconsole

	   Non-global zone console (slave side).
