HP StorageWorks Fabric OS 5.3.x administrator guide (5697-0244, November 2009)

114 Maintaining configurations
Restoring configurations in a FICON environment
If the switch is operating in a FICON CUP environment, and the ASM (active=saved) bit is set on, then the
switch ignores the IPL file downloaded when you restore a configuration. Table 26 describes this behavior
in more detail.
If fmsmode is enabled in a configuration file, but is disabled on the switch, the configDownload
command fails and displays an error message. This prevents undesirable conditions that could result from
enabling fmsmode on a switch that does not require it.
Downloading configurations across a fabric
To save time when configuring fabric parameters and software features, you can save a configuration file
from one switch and download it to other switches of the same model type, as shown in the following
procedure.
Do not download a configuration file from one switch to another switch that is a different model, because it
can cause the switches to fail. If you need to reset affected switches, then issue the configDefault
command.
NOTE: In some cases, the configRemoveAll root command is required for reset, in which case you
should contact your system administrator.
To download a configuration file from one switch to another same model switch
1. Configure one switch first.
2. Use the configUpload command to save the configuration information. Refer to ”Backing up a
configuration” on page 109.
3. First run configDefault on each of the target switches, and then use the configDownload
command to download the configuration file to each of the target switches. Refer to ”Restoring a
configuration” on page 111.
