EMC 300-000-978 REV A03 manual Rebooting and Custom Settings, Boot Device Support

PowerPath Administration on Solaris

socal connections, run the following commands to restore the paths in PowerPath:

On hosts running this OS	Run these commands
Solaris 7, 8, and 9	devfsadm
	powercf -q
	powermt config
Solaris 2.6	drvconfig; disks; devlinks
	powercf -q
	powermt config

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.
