Upgrading or downgrading the Wave Server 23-8
Chapter 23: Continuing System Administration
Wave Global Administrator Guide
• If you are planning to upgrade over a modem connection, be sure to check the size of the
upgrade CAB file. Uploads will take the longest over a modem. For example, if the
upgrade CAB file is 20 MB, expect a two-hour upload over a modem. For this reason,
only small HotFixes should be uploaded using a modem.
For instructions on how to upload a CAB file, see “Uploading and upgrading steps” on page
23-9.
Performing an upgrade
The automated upgrade procedure unpacks files, starts the SNMP Alarms applet (which runs
throughout the process so you can monitor the upgrade status), restarts the Wave Server, copies
files, restarts again, and verifies the upgrade. In addition, Wave may exercise an option to
automatically break and restore the disk mirror with the redundant hard drive for subsequent
upgrades, so that if the upgrade fails you can boot with your previous software version from the
second drive.
Note: When you start an upgrade, the SNMP Alarm panel pops up and you can monitor the
progress of your upgrade. If you have a browser pop-up blocker on your system, the SNMP
Alarm panel is blocked and doesn't come up. You can usually configure these blockers to allow
pop-ups from specific domains and IP addresses.
The upgrade checks the Wave software versions only. It does not check individual file versions.
The registry, Call Detail Report database, and files are backed up as they are replaced. If the
upgrade is successful and Wave is fully functional, the setup files are removed.
If you have mirrored disks, use the Disk Management to verify the health of your disks before
proceeding with an upgrade. For information about checking your disks using Disk
Management, refer to “Identifying RAID disk health” on page 23-40.
Caution: You cannot see any SNMP alarms during an upgrade unless trap destinations
are configured in the SNMP Configuration applet. For instructions, see “Configuring
SNMP agents” on page 23-27. In addition, be sure to run the Software Upgrade applet
over the LAN or modem, as shown in the next diagram, if you want to view SNMP
status.
