Configuring Fc Host Port Failover - Quantum Scalar i6000 Installation Manual

Configuring FC Host Port Failover

Configure the optional FC Host Port Failover (HPF) feature so that an alternate "standby" target port on an
I/O blade can assume the identity and LUN mapping configuration of the primary "active" target port if the
primary port fails. HPF enables the library to continue operations without requiring you to reconfigure the
host or the SAN.
To enable HPF, you must make sure that two ports on the I/O blade are in target mode and point-to-point
connection. Use ports 1 and 2, which are ports that are traditionally configured to be host targets. I/O blade
ports are numbered from bottom to top as the blade sits in the I/O management unit.
Both ports must be attached to the same SAN fabric to provide host access. The active primary port is used
for host communications, while the passive standby port is kept idle. The way that you configure the
recovery settings determines how the failed port behaves after it is restored from a failed state.
The library generates a ticket when port failover occurs. Examine the ticket and the repair page associated
with the ticket to determine the reason for the failover.
To configure HPF, perform the following steps:
1 Log on as an administrator.
2 Make sure that you are viewing the physical library. From the View menu, click the name of the physical
library.
3 Confirm that there are two ports on the I/O blade in target mode and point-to-point connection. For more
information, see "FC Host" in the Scalar® i6000 User's Guide.
4 Click Setup→ Connectivity→ FC Host Port Failover.
The FC Host Port Failover dialog box appears, showing all the I/O blades found in the library. Each
blade is identified by name and by location.
