Component --Identifier-- -------Description----------
PD Disk:32 ST3400755FC PD for cage type DC3 in cage position 2:0:0 is missing from
the firmware database
PD Suggested Action 6
Check the release notes for mandatory updates and patches to the HP 3PAR OS version that is
installed and install as needed to support this PD in this cage.
Port
Displays port connection issues:
Checks for ports in unacceptable states
Checks for mismatches in type and mode, such as hosts connected to initiator ports, or host
and Remote Copy over Fibre Channel (RCFC) ports configured on the same FC adapter
Checks for degraded SFPs and those with low power; perform this check only if this FC Adapter
type uses SFPs

Port Suggested Actions, General
Some specific examples are displayed below, but in general, use the following CLI commands to
check for these conditions:
For port SFP errors, use commands such as
showport, showport -sfp,showport -sfp
-ddm, showcage, showcage -sfp
, and
showcage -sfp -ddm
.
