5-184 Installing and Using Utilities
General Problems and Solutions
The table below describes some common problems that could prevent your system from passing the
readiness check.
IMPORTANT:
Never perform hardware maintenance, such as removing and replacing system components, while
the Active Upgrade process is running. If you experience a problem that prevents the Active
Upgrade process from completing successfully, you should always be able to abort the upgrade
session to restore your system to its original state.
Troubleshooting: Readiness Check
Error
IO board nn is unsafe to
pull
RDR disk is not duplexed
Embedded NIC not
teamed
No IP address on
Upgrade ready team
Team does not have link
on both sides
Active Upgrade may fail.
Check DHCP server.
Action
Verify that all critical system resources (including disks, Ethernet PCI
adapters, and VTMs) are configured correctly and duplexed. See
"Prerequisites" on page 5-106 for more information.
If you recently ran an upgrade session, wait for the RDR
resynchronization process to complete before running another
upgrade session. See "Verifying If RDR Disks Are Resynchronizing"
on page 5-183 for more information.
Use the PROset utility to configure your Ethernet PCI adapters into
teams. All embedded Ethernet PCI adapters must be teamed. See
"Prerequisites" on page 5-106 and "Recommendations" on page
5-108 for more information about configuring Ethernet PCI adapters.
Use the Network Connections control panel to assign an IP address
(preferably a static IP address) to the Ethernet team. See
"Prerequisites" on page 5-106 and "Recommendations" on page
5-108 for more information about configuring Ethernet PCI adapters.
Ensure that an embedded Ethernet team has at least one adapter in
each CPU- I/O enclosure with an active network link. Verify that the
network cables are plugged in on both sides, and that the Ethernet
team has a valid IP address. See "Prerequisites" on page 5-106 and
"Recommendations" on page 5-108 for more information about
configuring Ethernet PCI adapters
The Active Upgrade Console cannot obtain IP addresses from your
DHCP server. If possible, assign static IP addresses to your Ethernet
teams and VTMs to avoid problems during the Active Upgrade
process.
