Problem: Cannot initialize or create a system

This topic helps if your attempt to create a system has failed.
The failure is reported regardless of the method that you used to create a clustered
storage system:
v USB flash drive
v
v Service assistant
v Service command line
The create clustered-system function protects the system from loss of volume data.
If you create a clustered system on a control enclosure that was previously used,
you lose all of the volumes that you previously had. To determine if there is an
existing system, use data that is returned by "Procedure: Getting node canister and
system information using the service assistant" on page 53 or "Procedure: Getting
node canister and system information using a USB flash drive" on page 53.
v The node canister that you are attempting to create a clustered system on is in
v The partner node canister in the control enclosure is not in active state.
v The latest system ID of the control enclosure is 0.
If the create function failed because there is an existing system, fix the existing
clustered system; do not re-create a new clustered system. If you want to create a
clustered system and do not want to use any data from the volumes used in the
previous clustered system, go to "Procedure: Deleting a system completely" on
page 60, and then run the create function again.
You might not be able to create a cluster if the node canister (the one on which
you are attempting to create the clustered system) is in service state. Check
whether the node canister is in service state by using the data returned by
"Procedure: Getting node canister and system information using the service
assistant" on page 53 or "Procedure: Getting node canister and system information
using a USB flash drive" on page 53. If the node is in service state, fix the reported
node errors. For more information, go to "Procedure: Fixing node errors" on page
61. After the node error is corrected, attempt to create a clustered storage system
again.

Problem: Node canister service IP address unknown

This topic describes the methods that you can use to determine the service address
of a node canister.
A default service address is initially assigned to each node canister, as shown in
Table 19 on page 47. Try using these addresses if the node has not been
reconfigured, and the addresses are valid on your network.
If you are able to access the management GUI, the service IP addresses of the node
canisters are shown by selecting a node and port at Settings > Network > Service
IP Addresses.
If you are unable to access the management GUI but you know the management
IP address of the system, you can use the address to log into the service assistant
that is running on the configuration node.

candidate state. The node canister is in candidate state if it is a new canister.
