A Backup server with Windows 2003 and Symantec Backup Exec 12.5. The Daily Inventory Job has Error Reports with description: “incompatible storage media detected in robotic library”
A Dell PowerVault TL4000 Tape library with two LTO3 drives, with a yellow “Media Alert” LED on. The Web interface showed me that some tapes has been marked “Bad”, so that explained the Media Alert.
I do like to keep my posts up-to-date. This post would not be complete without mentioning VMware Labs fling, the PXE Manager for vCenter .
VMware PXE Manager is a management tool that supports automatic PXE boot (network boot using PXE) and automatic customization of large numbers of ESXi systems,
Other features are :
Automated provisioning of new ESXi hosts stateless and stateful (no ESX)
ESXi host state (firmware) backup, restore, and archiving with retention
ESXi builds repository management (stateless and statefull)
ESXi Patch management
Multi vCenter support
Multi network support with agents (Linux CentOS virtual appliance will be available later)
Wake on Lan
Hosts memtest
vCenter plugin
Deploy directly to VMware Cloud Director
Deploy to Cisco UCS blades
This fling is accompanied by instructions and two videos. The first one shows you how to install PXE manager and the second one shows you how to install a stateless ESXi server.
Introduction
Maybe it is because of my Linux background, one subject that always intrigues me is scripting. When work becomes routine, it is time for a script. Some time ago, I got involved in deploying VMware ESX 3.5 (Classic) and I had a nice time writing kickstart scripts. Especially the %post part was fun.
Then VMware announced ESX 4.1 will be the last version with the “Classic Console”, all future versions will be based on ESXi. At that moment I decided to say “Goodbye to the Console (and all the benefits)” and to concentrate on ESXi and meet the challenges that come with something new. The first one: Deployment.
One night, I was looking for information about memory management in VMware ESX. Of course, the first source of information is the vSphere Resource Management Guide. Chapter 3 provides some information on this subject.
