Troubleshooting 77
If you lose connection to the networks, you may have to use iLO to restore connectivity.
Unable to migrate host to management cluster
Symptom
The installation utility created the CS9Mgmt cluster in vCenter but is unable to migrate one of the ESXi
nodes from the default cluster to the new management cluster.
Cause
The installation utility is trying to create the CS9Mgmt cluster in vCenter and then migrate one of the ESXi
nodes from the default OneView InstantOn cluster to this new CloudSystem management cluster.
Because the installation utility runs on the management VM, the VM cannot be turned off and put into
maintenance mode for moving the host to the management cluster.
Action
If the utility encounters problems while attempting to move the host to the management cluster, you must
perform the following steps:
1.
Create a cluster (CS9Compute).
2.
Disable HA on the original cluster.
3.
For all hosts (except ESXi host that is the management VM), perform the following steps:
a.
Shut down the guest OS for the VSA VM and wait about a minute.
You may have to use the StoreVirtual CLI commands (for example, cliq getVolumeInfo) to
assess the status of volumes before this step can complete.
b.
Move the host to maintenance mode.
c.
Migrate the host to the new CS9Compute cluster.
d.
Move the host out of maintenance mode.
e.
Power on VSA VM.
4.
Enable HA on CS9Compute if there is more than one node.
5.
Enable DRS on CS9Compute node.
Both the management and compute clusters must have DRS enabled. If the compute cluster no
longer satisfies the minimum requirements for HA, it is disabled.
Trouble setting up storage
Symptom
Connectivity issues may occur when the installation utility attempts to allocate disk space from the VSA
cluster and make it shared between all ESXi hosts.
Explanation
The Installer is trying to allocate as close to 8TB of disk space as possible from the VSA cluster and make
it shared between all ESXi hosts. If the credentials are no longer viable, there may be connectivity issues.
After creating a volume in VSA, then an attempt is made to register the volume with the ESXi hosts. The
volume is assumed to be created with RAID-10.
Action
Use OneView for vCenter to allocate a datastore, or use the following steps to create it manually:
1.
Launch the StoreVirtual Centralized Management Console.
2.
Log in to the VSA Cluster (as specified in OneView InstantOn, default is HP-HyperConv-XXX).
Credentials were supplied during the OneView InstantOn setup.
3.
Create a CS9MgmtDatastore volume with as close to 8TB of space (RAID-10) as possible.
