About changing host settings and information
You can change host settings and update previously registered host information.
Depending on how a host is registered, you change host settings and information by using either of
the Refresh Hosts or Edit Hosts options. The Refresh Hosts option updates a host by obtaining
information from the Host Data Collector or Device Manager agent. The Edit Hosts option allows you
to manually change host settings.
If a host accesses storage using a Fibre Channel (FC) or Fibre Channel over Ethernet (FCoE) connection,
you must change host group names, host modes, and host mode options using the Edit Hosts option.
You can update other host-related information when replacing host HBAs by exchanging the WWN
settings in the LUN paths so that the new HBA inherits the WWN settings from the old HBA. Perform
this settings exchange by using the Exchange HBAs dialog box when you replace a host HBA due to
failure, or by using the Add HBAs dialog box and the Remove HBAs dialog box when you complete
a planned HBA replacement as part of scheduled maintenance to prevent performance degradation.
TIP:
The settings for the host WWN are not linked to the settings for the host group on the storage system
side. For example, even if you delete the host WWN , the WWN is not deleted from the host group.
To delete the WWN after replacing HBAs, use the Remove HBAs dialog box. To delete the WWN
from a host group at a time other than when replacing an HBA, use the
ModifyPort command.
For details about using the ModifyPort command, see the HP XP7 Command View Advanced
Edition CLI Reference Guide.
