ainfo satprep_patch_freeze

satprep_patch_freeze.py is a script that automatically clones software channels of subscribed systems. It also binds affected systems to cloned channels. This can be very useful when planning software maintenance for enterprise-grade multi-tier applications and a high amount of systems.

#Implementation To run the script you need to specify a Satellite server and systems or group names that should be cloned. By default, the script will do the following:

1. Scan the systems and/or groups for base-channels and child-channels
2. Clone the appropriate channels
3. Assign the cloned channels to the affected systems

The script also allows undoing these changes after maintenance tasks.

#Parameters

##Generic Options

Parameter	Description
-d / --debug	enable debugging outputs (default: no)
-n / --dry-run	only simulates updating custom keys (default: no)
-u / --unfreeze	removes clones and remaps systems (default: no)

##Server Options

Parameter	Description
-a / --satellite-authfile	defines an auth file to use for Satellite
-s / --satellite-server	defines the Satellite server to use (default: localhost)

##System Options

Parameter	Description
-S / --system	specifies a system to use for freezing patches
-g / --group	specifies a system group to use for freezing patches
-e / --exclude	defines hosts that should be excluded for freezing patches
-i / --no-remap	disables remapping affected systems to cloned channels (default: no)

##Channel Options

Parameter	Description
-A / --all-subchannels	clones all sub-channels instead of only required ones (default: no)
-l / --label	defines a label for the cloned channel (e.g. application name)
-D / --date	defines the date patches should be freezed (default: current date)

#Examples Freezing software channels for a particular host:

$ ./satprep_patch_freeze.py -s tvm-spacewalk02.test.loc -S tvm-web01.test.loc -l "webtier"

Simulate unfreezing software channels for a particular host. Satellite authentification is done using an auth file:
