Rebooting and Custom Settings
On every reboot, all saved custom files
(
/etc/powermt.custom.[0-2]) are incremented by one version. Thus,
at any time, the custom configurations from the last three reboots are
available.
You can ascertain from the custom file timestamps which version of
the custom file contains the last valid settings saved prior to a reboot.
To restore a custom configuration, enter the following commands:
/etc/powermt load file=/etc/powermt.custom.<desired version>
/etc/powermt save
Although you can restore an earlier powermt.custom file, it is not
currently possible to restore an earlier emcp_devicesDB file.
Boot Device Support
Solaris can boot from either a native device or pseudo device. Only
pseudo devices (emcpower devices), however, support booting with
failed paths. Refer to Chapter 3, Configuring a PowerPath Boot Device
on Solaris, for more information.
