Managing host I/O timeouts for an online upgrade

The default values for host operating parameters such as LUN timeout and queue depth are typically set

to values that ensure proper operation with the stora ge system. These values are appropriate for most

storage system operations, including online ﬁrmware upgrades. In general, host LUN tim eouts of 60

seconds or more are adequate to accommodate an online upgrade. In most situations it will not be

necessary to alter these settings to perform an online ﬁ rmware upgrade.

If any host timeout values have been decreased to less than 60 seconds, it will be necessary to reset

them to their original default value. The following section provide a summary of the steps and com m ands

involved in checking and changing timeout values for each supported operating system. See the

operating system documentation for more information.

NOTE:

Unless otherwise noted, cluster testing with online controller ﬁrmware upg rades has not been completed.

Cluster information will be added to this document when the testing is complete.
