Configuring the switch 134
Enabling Alternate Control Prohibited
You can display ACP in the Configure menu by selecting the check box to set the ACP on or off.
When the ACP is checked, alternate control prohibited is on and alternate managers cannot
change FICON switch connectivity parameters.
The switch connectivity parameters include all configuration changes including blocking ports,
beaconing ports, clearing, LINs, CTP switch over and so on. The alternate managers include CLI,
EWS and SNMP, but do not include the host via in-band management.
The ACP setting is only controlled by the HAFM and cannot be changed by host programming.
Select the option again to remove the check mark and disable Alternate Control Prohibited.
CAUTION: The Alternate Control Prohibited check box is visible only for switches that support ACP.
Prior to sending the ACP setting to the switch, confirm the warning dialog box that states you are
about to disable alternate configuration control.
Backing up and restoring configuration data
You can back up the NV-RAM configuration, which includes all of the data you input through the
instructions in this chapter, using the Backup and Restore Configuration option. This option is
available through the Maintenance menu. Choosing this option backs up the configuration data
to a file on the HAFM appliance hard drive. The restore function writes this data back to NV-RAM
on the switch. Using the restore function overwrites the existing configuration. For more information,
see ” Backing up and restoring configuration ” on page 158.
In addition to the Backup and Restore Configuration option, the backup application
automatically backs up configuration and other critical data from the HAFM appliance. As long as
backup media remains in the backup drive of the HAFM appliance, data is written to the backup
media whenever the directory contents change or you reboot the HAFM appliance. For more
information, see ” Backing up and restoring Element Manager data ” on page 42.
NOTE: HP does not recommend changing the default backup settings.
CAUTION: To ensure trouble-free backups, it is imperative that you leave the backup media in the
drive at all times. Removing the media during a backup or restore can corrupt the database on the
media.
When data is being written to or read from the backup drive, the CD-RW drive write LED flashes.
Make sure this LED is not flashing before you remove the media.
