0xxxxx connection error codes

If the HMC displays a state of No Connection in the managed system state column, it means that the HMC is unable to establish a connection to the managed system. There are several reasons why the HMC fails to establish connection, and often it is due to network issues. It is important to first check the network setting on both the HMC and the managed system. However, there are times a no connection state is caused by another problem unrelated to network settings. Use the following tables to find the error code you are receiving, and the recovery action if available.

Choose the range from the list below:

0x00xx
0x01xx
0x02xx

0x08xx
0x0Bxx
0x10xx

Range 0x00xx: Connection related failures during runtime (after initial command sequencing is complete)

0x00xx error codes (hex)	Text displayed	Recovery action
0x0000	Connecting
0x0001	Connecting	If the HMC does not recover automatically within a few minutes, do the procedure in Resetting the managed system connection from the HMC. If the managed system is still showing `No Connection` on the HMC, contact your next level of support or your hardware service provider.
0x0002	Connecting	If the HMC does not recover automatically within a few minutes, do the procedure in Resetting the managed system connection from the HMC. If the managed system is still showing `No Connection` on the HMC, contact your next level of support or your hardware service provider.
0x0003	Connecting	A reset connection of the managed system was initiated on the HMC. If the HMC does not recover automatically within a few minutes, contact your next level of support or your hardware service provider. Note: The managed system should not stay in this state for long. The HMC will re-establish connection to the system, and change to another state.
0x0004	Temporary disconnection
0x0005	Permanent disconnection
0x0006	Forced disconnection	If you no longer want your server to be HMC-managed, you must reset the server to a nonpartitioned server before removing the HMC. See Resetting the server to a nonpartitioned configuration for details.
0x0007	Connecting	If the HMC does not recover automatically within a few minutes, do the procedure in Resetting the managed system connection from the HMC. If the managed system is still showing `No Connection` on the HMC, contact your next level of support or your hardware service provider.
0x0008	Duplicate IP	There is another managed system with the same IP address. Check whether there is an IP conflict. See Check for IP conflict. Reset the managed system connection from the HMC. See Resetting the managed system connection from the HMC for details. If the managed system is still showing `No Connection` on the HMC, contact your next level of support or your hardware service provider.
0x00FF	Connecting	Reset the managed system connection from the HMC. See Resetting the managed system connection from the HMC for details. If the managed system is still showing `No Connection` on the HMC, contact your next level of support or your hardware service provider.

Range 0x01xx: Socket-level connect failures

0x01xx error codes (hex)	Message	Recovery action
0x0101	DNS failure	The HMC is unable to resolve the host name entered for the managed system through the domain name server. Check whether the DNS is down. If the failure continues, remove the managed system connection and add it back using the IP address. Note: Leaving a connection in the DNS failed state might cause performance problems for other HMC connections.
0x0102	Connecting	The HMC is unable to establish a network connection to the managed system. Ensure that the managed system network is configured correctly.
0x0103	Connecting	The target IP address of the managed system is refusing a connection from the HMC. Ensure that the IP specified is a valid managed system IP and that the managed system's network is configured correctly. A connection might also be refused if the service processor firewall is configured to block this HMC IP address. Check the network configuration setting of your managed system to ensure that the HMC IP is not being blocked.
0x0104	IP unreachable	The HMC is unable to establish a network connection to the managed system. Ensure the HMC and managed system are not on either side of a firewall, or if a firewall exists, ensure that the firewall is configured correctly. Ensure that the managed system network is configured correctly. A common cause for this might be an invalid IP configuration on the HMC (for example, bad routing tables or default gateway).
0x01FF	Connecting	The HMC is unable to establish a network connection to the managed system. Ensure that the managed system network is configured correctly.

Range 0x02xx: SSL level connect failures

0x02xx error codes (hex)	Message	Recovery action
0x02FF	Connecting	The HMC is unable to establish a secure network connection to the managed system. Reset the connection from the HMC. See Resetting the managed system connection from the HMC for details. If the problem persists, contact your next level of support or your hardware service provider.

Range 0x04xx: Interface version related connection failures

0x04xx error codes (hex)	Message	Recovery action
0x0401	Interface version timed out	If the HMC does not recover automatically within a few minutes, do the procedure in Resetting the managed system connection from the HMC. If the managed system is still showing `No Connection` on the HMC, contact your next level of support or your hardware service provider.
0x0402	Already connected	The managed system already has a connection established from the same HMC. If the HMC does not recover automatically within a few minutes, do the procedure in Resetting the managed system connection from the HMC. If the managed system is still showing `No Connection`, then restart the HMC. If the problem persists, contact your next level of support or your hardware service provider.
0x0403	All connections in use	All connections available for HMCs are already in use. Determine what other HMCs are connected to the managed system, and remove the managed system connections from the other HMCs. Note: Contact your administrator to find out which HMCs can connect to the managed system.
0x0404	Version mismatch	This version of HMC is unable to manage the system. Update the HMC image.
0x0405	Duplicate MTMS	There is already a managed system with the same machine type, model, and serial number. Contact your next level of support or your hardware service provider.
0x0406	Firmware not ready	If the HMC does not recover automatically within a few minutes, do the procedure in Resetting the managed system connection from the HMC.
