Detecting Duplicate IP Addresses
As of RVU J06.10 / H06.21, CIP detects duplicate IPv4 addresses and MAC addresses in a subnet.
When a duplicate IP or MAC Address is detected, EMS Event 5230 will be created. One of these
alarms will be created:
• Duplicate CLIM IP Address: A duplicate IP address has been detected within the same network
and a potential loss of network connectivity for sockets using that source IP address may occur.
This alarm must be manually deleted.
• Duplicate CLIM MAC Address: A duplicate MAC address has been detected within the same
network and a potential loss of network connectivity through the interface with that MAC
address may occur. This alarm must be manually deleted.
Displaying Link Speed
Use ethtool to display the speed of a link. The syntax is:
ethtool interface-name
where interface-name is eth1, eth2, etc. Example 14: Ethtool Link Speed Display shows the
display:
Example 14 Ethtool Link Speed Display
ethtool eth1

Verifying the lunmgr Configuration of Two Storage CLIMs
To provide fault tolerance, two storage CLIMs must always be connected to the same physical disk.
Each storage CLIM identifies the disks connected to it and assigns a LUN to each device. This LUN
must match between the two CLIMs. If they point to different physical devices on the two CLIMs,
neither path to the disk can be started. This can occur when one storage CLIM in a pair is replaced
or a new enclosure is added or removed.
To detect LUN configuration problems, use the CLIMSCMP tool. The syntax is:
CLIMSCMP [/out out-file | /outv var-name] clim-name-1 clim-name-2
out out-file
Directs the display text to the file out-file.
outv var-name
Directs the display text to the variable var-name.
