Dynamic
Reconfiguration/Alternate Pathing Setup
This setup will only take one
reboot.
Applications Setup
Install Alternate Pathing 2.2 for Solaris 7 Only (bundled with Solaris
on Supplement CD), IP Multi-Pathing should be used for Solaris 8.
Install Sun Management Center 3.0 (optional). Included in Solaris
8 Media Kit or download from http://www.sun.com/solaris/sunmanagementcenter/
Dynamic Reconfiguration Setup
OS : Solaris 2.7 5/99 or higher
Boot Prom Version: 3.2.29
You may need to download patch 103346-29 to update the prom version.
Install recommended pathes for Solaris 7 or Solaris 8 from http://sunsolve.sun.com
Modify the /etc/system file:
set pln:pln_enable_detach_suspend=1
set soc:soc_enable_detach_suspend=1
set kernel_cage_enable=1

Alternate Pathing Setup for Networking For Solaris 7 Systems Only
- Software version: Alternate Pathing 2.2
- Alternate pathing database to store Alternate pathing data: A dedicated
disk slice(s) at least 300Kbytes.
You might need to change your filesystem layout to accommodate for this
disk slice.
command: #apdb -c raw-disk-slice
(-f)
example: #apdb -c /dev/rdsk/c0t0d0s6
-f
- Alternate pathing your primary network interface to a backup network
interface. This will create a meta network path group.
command: #apnet -c -p primary-network-interface
-a backup-network-interface
#apdb -C
example: #apnet -c -p hme0 -a hme1
- To check your alternate pathing configuration
command: #apconfig -N
- Rename /etc/hostname.primary-network-interface to /etc/hostname.m
primary-network-interface
example: #mv /etc/hostname.hme0 /etc/hostname.mhme0
Boot Prom Setup
- Issue a command to bring down your system to the boot prom:
command: #init 0
- Turn off memory interleaving
command: ok setenv memory-interleave min
command: ok boot
Alternate Pathing Commands for Networking for Solaris 7 Systems Only
In order to dynamically reconfigure a S-Bus board with a primary network
interface, you have to redirect the network traffic to the back-up network
interface.
command: #apconfig -P mprimary-network-interface-abackup-network-interface
example: #apconfig -P mhme0 -a
hme1
To switch the network traffic back to your primary network interface,
issue this command:
command: #apconfig -P mprimary-network-interface-aprimary-network-interface
example: #apconfig -P mhme0 -a hme0
