Chapter 6 Installing and Configuring SunStorEdge Volume Manager 69
These commands create a startup script that enables the VolumeManager to exit
back to the OBP upon encountering a stale boot plex, allowing the VolumeManager
to try alternative boot disks.

Enabling Recovery Behavior and Boot Disk Detection

Toenable correct recovery behavior and boot disk detection, make the following
changes to the startup file /etc/rc2.d/S95vxvm-recover:
Make the edits exactly as shown, commenting out the vxrelocd line and with the
complete path to vxbootcheck. Be sure to append an ampersand to the
vxbootcheck line.
The default behavior of SunStorEdge Volume Manager when a physical disk fails is
not compatible with the hot-plug of HDD modules on the Netra ft1800. By default,
when the VolumeManager detects I/O failure on mirrored volumes, it restores
redundancy by relocating the objects to spare disks. This is called hot relocation.You
need to disable this default behavior.By commenting out the vxrelocd line, as
shown above, you prevent hot relocation.
Youmust repeat all these modifications after system upgrades.
Initializing the VolumeManager
When you have loaded the SunStorEdge Volume Manager, run vxinstall as
described in the Sun StorEdge VolumeManager Installation Guide . This section
describes the special actions you must take to initialize the VolumeManager for the
Netraft 1800.
Note – VolumeManager mirroring provides the fault tolerance for disk storage on
the Netraft 1800. This is provided by default when you add a disk to the Volume
Manager provided you have added the required lineto /etc/default/vxassist
as described in “Setting Default VolumeCreation” on page 68.
