NimbostratusGTM control?
I've installed the SnapIn, and it works great against my LTMs. However my immediate need is to script jobs against my GTMs. When I view the available commands, I don't see anything GTM-specific:
> Get-F5.iControlCommands
Add-F5.LTMPoolMember Add-F5.LTMVirtualServerRule Disable-F5.LTMNodeAddress Disable-F5.LTMPoolMember Disable-F5.LTMVirtualServer Download-F5.Configuration Download-F5.File Enable-F5.LTMNodeAddress Enable-F5.LTMPoolMember Enable-F5.LTMVirtualServer Get-F5.ConfigurationList Get-F5.DBVariable Get-F5.iControl Get-F5.iControlCommands Get-F5.LTMNodeAddress Get-F5.LTMPool Get-F5.LTMPoolMember Get-F5.LTMPoolMemberState Get-F5.LTMRAMCacheEntries Get-F5.LTMRule Get-F5.LTMVirtualServer Get-F5.LTMVirtualServerRule Get-F5.LTMVirtualServerStatistics Get-F5.ProductInformation Get-F5.SystemCPUUsage Get-F5.SystemDiskUsage Get-F5.SystemFanUsage Get-F5.SystemId Get-F5.SystemInformation Get-F5.SystemMemoryUsage Get-F5.SystemPowerUsage Get-F5.SystemTime Get-F5.SystemTimeZone Get-F5.SystemUptime Initialize-F5.iControl Load-F5.Configuration Move-F5.LTMPoolMember New-F5.SharePoint2007Deployment Remove-F5.Configuration Remove-F5.File Remove-F5.LTMPoolMember Remove-F5.LTMRAMCacheEntries Remove-F5.LTMVirtualServerRule Remove-F5.SharePoint2007Deployment Rollback-F5.Configuration Save-F5.Configuration Set-F5.DBVariable Set-F5.LTMPoolMemberState Upload-F5.Configuration Upload-F5.File
I can initialize a connection to the GTM and some of the basic and system commands work fine, but what I would like to use is something like Disable-F5.GTMPoolMember / Enable-F5.GTMPoolMember.
Is there currently a way to do this with the SnapIn? If not, are there any future plans to incorporate GTM commands?

Ned_66277I dug a little bit, and found out this is the function I want to use:
(get-f5.icontrol).GlobalLBPoolMember.set_enabled_state(pool, member/state)
I know what information I need to pass to it, but it apparently wants a particular struct passed to it (MemberEnabledState) that I can’t figure out how to declare:
http://devcentral.f5.com/wiki/default.aspx/iControl/GlobalLB__PoolMember__set_enabled_state.html- Sorry for not posting sooner, I didn't have all my email alerts setup correctly for the new social groups. I wasn't ignoring you - I promise B-).
Good investigation on your part. The Get-F5.iControl cmdlet will return an iControl.Interfaces object that contains members for all of the iControl top-level interfaces. The other cmdlet's were written as utility functions around the main interfaces, but this cmdlet will give you full access to the entire API.
With that said, I'll go ahead and writeup a script and post it later this morning that should get you going. I'll reply to this thread when I'm done.
Again, sorry for the delay...
-Joe - Ned_66277Specifically what I'd like to do is disable a particular GTM pool member in a script (and enable that same member in another script). Something like this (with the correct syntax of course):
(get-f5.icontrol).GlobalLBPoolMember.set_enabled_state("pool_sqlinstance1", "10.1.1.72:0", "STATE_DISABLED")
and
(get-f5.icontrol).GlobalLBPoolMember.set_enabled_state("pool_sqlinstance1", "10.1.1.72:0", "STATE_ENABLED") - As promised, here's a script that will query a GTM's Pools and Pool Members and allow you to get and set the state of the pool members. Let me know if you have any questions:

Joe, thank you very much for your reply and code. I tried using this a few different ways but it doesn't want to work for me. Am I calling this incorrectly?

This must have something to do with the array conversion from the structure to a 1-d and then a 2-d array. I'll dig in and see what's up with the object conversion into arrays, but that should work the way I did it.
-Joe - Ok, I've updated the script with more explicit type casting on the 1-d and 2-d array creation. Let me know if this works
http://devcentral.f5.com/wiki/default.aspx/iControl/PowerShellGTMPoolMember.html
-Joe - Now at least those make sense. I didn't provide mappings for the friendly states of "enabled" or "disabled". You need to use the true enumeration values of STATE_ENABLED or STATE_DISABLED on your command line.
PS> ./GTMPoolMember.ps1 gtm1 admin ******* pool_sqlinstance3 10.1.2.70:0 STATE_ENABLED
-or-
PS> ./GTMPoolMember.ps1 gtm1 admin ******* pool_sqlinstance3 10.1.2.70:0 STATE_DISABLED
Hopefully this works now. Sorry about the hassle here, I should have provided you with better example usages.
Again, if this doesn't work for you, please let me know.
-Joe - Ned_66277Yes, it works! I am happy, thank you so much for your help!
Araiot_156251Hi to All,
I was looking for examples on the commands but they are blank... so i got to ask how do i use the Save-F5.Configuration command, please provide an example. And what is [-Mode]
