▼ To Upgrade Software
If you have multiple hosts on your SAN, you can upgrade them simultaneously or
one at a time without affecting your SAN environment. Hosts that are not being
upgraded will not be affected during the upgrade. You can upgrade the host
software one host at a time or several hosts in parallel.
Caution – Your system will be unavailable to users and the SAN during the
upgrade procedure.
The order in which the SAN components should be upgraded is as follows:
1. Familiarize yourself with the required software components, versions and
patches.
See Chapter 3, TABLE 3-1 , “Minimum Software Component Versions and Patches” on
page 38.
2. Back up all data.
