First points to confirm

Verify that the cables of the storage system and network peripheral devices are connected correctly.

Simple errors such as disconnection of network cables might often cause a failure.

Verify that power is supplied to the storage system and network peripheral devices.

If power to the storage system stops, you must restart the storage system after power supply is restored.

Verify that you performed the necessary tasks by using the correct procedure as described in the manual.

Verify again of the content of the notes and cautions described in the procedures.

When operating with the REST API/CLI or maintenance node (adding and replacing nodes, changing and setting configuration information, importing and exporting configuration files), verify that the access-destination address is correctly specified.

Specify the correct IP address or host name for the storage cluster or individual storage node that you want to work with. For information on how to address the CLI, see VSP One SDS Block CLI Reference.

When operating with the REST API/CLI or maintenance node (adding and replacing nodes, changing and setting configuration information, importing and exporting configuration files), and the FQDN is specified for the destination, verify that the name resolution can be properly performed.

• Verify that the DNS setting is completed.

• Verify the path to the DNS server for any failures.

• Verify that the DNS server is running.

• Verify that the DNS record is correctly set for the FQDN. ¹

1. When changing and setting configuration information, a changed IP address of the control network might be set as a DNS record for the FQDN.

When using REST API/CLI, verify that the parameters and other options are correctly specified.

See the VSP One SDS Block REST API Reference or VSP One SDS Block CLI Reference.

When operating with the REST API/CLI/GUI or maintenance node (adding and replacing nodes, changing and setting configuration information, importing and exporting configuration files), verify that the SSL communication setting is correctly set.

For more information, see Establishing an SSL/TLS session for operation and management.

When operating with the maintenance node(installation, addition, replacement, changing and setting configuration information, importing and exporting configuration files, and creating the configuration backup file), verify that the SSL communication with VMware vCenter Server is correctly set.

For more information, see Establishing an SSL/TLS session for operation and management.

Verify that the external servers accessed by the storage system are configured and operating normally.

• The storage system works in cooperation with multiple external servers.

• If the external servers are not set correctly, a failure might occur. Verify that the following external servers are configured and operating normally.

  • Maintenance node audit log transfer server (external Auditd server)

  • External authentication (LDAP) server

  • DNS server

  • iSNS server

  • NTP server

  • SMTP server

  • SNMP manager

  • Syslog server

• A user of the storage system might have to be registered with an external server, such as an LDAP server.

Verify that the control network, compute network, and internode network that constitute VSP One SDS Block are all running normally.

• A failure that occurred in the network affects the storage system.

• Use a network monitoring system or survey terminal that is independent of the VSP One SDS Block to check if there are any failures or performance degradation (switch failure, link failure, increased delay, increased packet loss, connection at unexpected link speed and duplex operating values, etc.) in the network.

• If the network is redundant and recovery processing such as switching to the redundant route is occurring due to a failure, check the log of the switch or VMware ESXi, and verify that the time required for the recovery process meets the recovery time confirmed by customer support.

• If you have installed a firewall on each network and are filtering using TCP / UDP port numbers, contact customer support and ask them to check if the TCP / UDP port number required for each communication is set to be allowed.

• When temporarily connecting an investigation terminal to the internode network for fault isolation, be sure to disconnect after the fault isolation is completed, and verify that the network is closed with no connections other than the internode network port of the VSP One SDS Block node and the network monitoring system.

• For details about how to verify operation of ESXi and vCenter Server, see the VMware documentation.

• For information on how to check the monitoring system and switch of the network independent of the VSP One SDS Block, refer to the manual of each vendor.

Verify that the hardware of each storage node is operating normally.

For details about how to verify that hardware is operating normally, see the hardware vendor documentation.

Verify that the hardware of each storage node is configured correctly.

If the serial number and model name are not set, the storage node will fail to build. Check your hardware vendor's manual for information on how to set up your hardware.

Verify that the VM on each storage node is operating normally.

For details about how to verify normal VM operation and specify the VM settings, see the VMware documentation.

If all the VMs are suspended due to a commercial power failure or power unit failure, start the storage cluster (contact customer support).

Verify that vNIC and other virtual settings for the VM on each storage node are specified correctly.

Verify that ESXi and vCenter Server are operating normally.

For details about how to verify operation of ESXi and vCenter Server, see the VMware documentation.

Verify that ESXi and vCenter Server are set up correctly.
