Firmware FAQs and Troubleshooting

Q.What kinds of job logs are available?

A.There are two kinds of job logs: Job run log and the jobvm log.

The job run log is where events are logged for a particular job’s run. This log can be used to check what went wrong with the job and make any required corrections. The job run log can be viewed by selecting a particular job from the job list, then clicking Job Run Detail. From the window that pops up, select a particular run for the job, then click Job Run Log.

The jobvm.log is a global log for all types of jobs. It is used mainly for development troubleshooting. The jobvm.log can be viewed by selecting Admin > Appliance > View Log File, then clicking jobvm.log.

Q.How many devices can I have in one firmware job?

A.There is no limit, although it is recommended that you work with device groups and set up jobs accordingly (for example, by location or building). The WLSE can run 10 jobs in parallel. While a job is running, the WLSE allocates resources for updating 20 devices in parallel. At any given time, 20 devices will be upgrading and the remainder will be waiting for resources to become available.

Creating a single job with more than 100 access points is not recommended. If you are updating the firmware on a large number of access points, you might want to convert a few APs initially to get familiar with the process. Once you are familiar with the process, you can create a job with 20 devices, then increase the number of devices if no devices are failing. By running a smaller job, you will also know how much time it takes for the job to complete.

Q.Can I give a firmware job a name that is used for a configuration or radio management job?

A.No. Job names cannot be duplicated.
