Wanted to see the NTP servers configured for a UCS. If anyone wants to edit up a version that can read a list of UCS IP’s and report back all NTP servers per UCS, that would rock. Thanks!

Hope this helps someone on their path towards enlightenment.

# Check module dependencies

if ((Get-Module |where {$_.Name -ilike “CiscoUcsPS”}).Name -ine “CiscoUcsPS”)

{

Write-Host “Loading Module: Cisco UCS PowerTool Module”

Import-Module CiscoUcsPs

}

$UcsmAddress = “172.16.0.1”

#Get Credentials

$Creds = Get-Credential

 

#define UCS connection

$UCSMHandle = Connect-Ucs $UcsmAddress $creds #Connect to the UCS

 

#Get NTP Server

Get-UcsNtpServer -Ucs $UCSMHandle

How to SSH from a Linux Server to a UCS in Active Directory.

Below is an example, edit for your needs.

ssh “ops.realworlducs.com\craig”@172.23.227.1

Protect yourself, fiber light isn’t your friend.

These cover the Wavelengths for 1g and 10g ethernet fiber, and up to 16g FC. Believe they cover DWDM also.
Good to have a few of these on hand at your datacetner. And let’s face it, they look Swanky! :)

One UCSM to Rule them All

One UCSM to Rule them All

After dealing with over 1000+ UCS blades… the 15% of blades that are bare metal are exponentially more trouble than the 85% running ESX. Bare Metal kills managing UCS effectively. Code updates become impossible quickly using bare metal unless servers can be rebooted and drivers updated on the OS regularly. Especially with a diversity of Bare Metal servers on a UCS this can leave blades in “Pending” indefinitely.

“Just say No” to Bare Metal on UCS (unless it is an ESX or Hyper-V Server).
