Dell DX6000 Примечание к выпуску - Страница 4

• The CSN Console supports web-based, post-boot modification of network services configuration,

user access for both the admin interface and SNMP, software image management, and

configuration for DX Storage, the SCSP Proxy and Content Router.

• A Backup and Restore section in the CSN Console provides management of automatic

configuration file backups created by the CSN and saved into the DX Storage cluster. Additionally

the interface allows administrators to trigger a manual configuration file backup and restore a

backup manifest in the event of a system failure. Please see the 'Configuration File Backup and

Restore' section of the CSN Installation and Configuration Guide for additional details.

• A Licensing section in the CSN Console surfaces the ability to add and delete individual license

capacity and hardware compatibility keys and to publish these keys into an aggregate license file

used by the DX Storage cluster. Please see the 'Configuring Object Storage Cluster Licensing'

section of the CSN Installation and Configuration Guide for additional details.

• The CSN includes an SNMP MIB with operational and status information for all nodes in the

associated DX Storage cluster. Additionally, SNMP MIBs for both DX Content Router Publisher

and Replicator are available on the CSN.

1.4. Limitations of this Release

These are the known issues and operational limitations that exist in this release of DX Storage CSN.

• Automatic Backups with Server Reboots A server restart will trigger an automatic configuration

file backup due to an update to the firewall rules that occurs during shutdown.

• DX Storage Authentication and Authorization via Curl The version of curl included by

default in Red Hat version 5.5 is not recent enough to properly handle the authentication and

authorization features in DX Storage version 5.0. Integrators wishing to use curl to take advantage

of these new features will either need to compile a more recent version of curl on the CSN or use

a different server that already has a more recent version.

If upgrading a previously installed CSN to a new version, the same install script used for a new

installation can be used. Upgrade does not require any reconfiguration and all service states are

preserved from their previously configured values. The CSN will need to be rebooted after the

software is updated so administrators may wish to schedule the upgrade during off peak hours to

ensure DX Storage and DX Content Router activity are not disrupted.

Please refer to the Installation and Configuration Guide for step-by-step upgrade instructions.

Special attention should be paid to the following items when configuring a CSN. More details can be

found in the CSN Installation and Configuration Guide.

• RedHat Administrative Tool Compatibility Both the RedHat Network Administration Tool and

the RedHat Security Level Configuration Tool are incompatible with the CSN because they alter

the expected location and/or configuration of critical network and firewall configuration files,

possibly interfering with initial CSN configuration or communications. To prevent conflicts, these

tools are removed during installation of the CSN.

• SELinux Errors While SELinux is run in permissive mode during the bootstrap process, SELinux

errors may still appear during bootstrap. These errors can be safely ignored and will not occur

again after a system reboot.
