To switch to an alternate DX Storage software version, select the desired version and click 'Update'. This will change the software image used to network boot all DX Storage nodes. The DX Storage cluster must be rebooted to pick up the new version. You may reboot the DX Storage cluster all at once or with a rolling upgrade one node at a time from the DX Storage admin console to pick up the new version. Note Prior to rebooting, you may wish to suspend volume recovery from the DX Storage Admin Console or SNMP if using a rolling upgrade to prevent cluster churn as individual nodes reboot. Please reference the DX Object Storage Getting Started Guide for complete details on suspending volume recovery. 3.4. Editing User Access The username used to access the CSN console is 'admin'. The admin password can be updated from the User Access link under the Cluster Services tab. The default password is 'dell'. Characters are obscured when entered on the page so double entry is required to ensure accuracy. The obscured character count does not necessarily correspond to the number of characters in the password. Copyright © 2010 Caringo, Inc. All rights reserved 15 Version 2.0 December 2010

To switch to an alternate DX Storage software version, select the desired version and click 'Update'.

This will change the software image used to network boot all DX Storage nodes. The DX Storage

cluster must be rebooted to pick up the new version. You may reboot the DX Storage cluster all at

once or with a rolling upgrade one node at a time from the DX Storage admin console to pick up the

new version.

Note

Prior to rebooting, you may wish to suspend volume recovery from the DX Storage Admin

Console or SNMP if using a rolling upgrade to prevent cluster churn as individual nodes

reboot. Please reference the DX Object Storage Getting Started Guide for complete

details on suspending volume recovery.

3.4. Editing User Access

The username used to access the CSN console is 'admin'. The admin password can be updated

from the User Access link under the Cluster Services tab. The default password is 'dell'. Characters

are obscured when entered on the page so double entry is required to ensure accuracy. The

obscured character count does not necessarily correspond to the number of characters in the

password.
