vROPS Changing Node Address

17/03/2015 // 0 Comments

Hello, Vmware made a great leap forward for Operations Manager renamed vRealize Operations Manager. It’s 6.0.1 version is already out. Unfortunately, there are some manual processes on some settings including Node Address change and IP change of nodes. I try to ease these operations with this guide. Recently, I had some issues about the “Node Address” of a node, I needed to change the DNS entry of a Remote Collector (Not IP Address), after some research I finally found a quick way to do it. As you can see below picture remotenode01 dns name is seen to be remotenode3.vsphere.local (or the node name is wrong) and I want to fix that. Changing the IP address is a tricky process and there are some guides in blogs. I will try to explain changing the DNS name of an any node. You can check the “Resources” if you want to change the IP address of the nodes. Before starting anyting Check the version of the vROPS, I did this with 6.0.1. Snapshot! Get the snapshot of “ Snapshot! Get the snapshot of “ALL NODES“. Enable the SSH service on all nodes by using this command:  service sshd start Open SSH consoles for all nodes. Open Admin panel of vROPS (https://yourvropsmasternodeaddressorip/admin) Process Open the Admin panel of Master node and take Cluster Offline. Wait for all nodes to be offline. Open SSH sessions; beginning with Master Node, stop the vmware-casa service for each node:  service vmware-casa stop Open this file with your favorite editor:  /storage/db/casa/webapp/hsqldb/casa.db.script Find the  ip_address  entry, there should be one for all nodes. There is a slice_name  entry but I guess it is just visual name of the nodes, so you can try to change it too. Change the old IP address or DNS address with new one in the file for all nodes. Save and exit. Beginning with Master node, start […]

How to extend LVM disks in vCenter

LVM disk extension can be a challenging experience for who are not familiar with unix environment.  I will try to explain it as simple as possible in this guide. Heads up: You need to reboot the virtual machine twice! There is no live-extension way for LVM in vSphere environment. If you want to do it live-extension, you need to add new VMDK hard disk to the VM and extend in the LVM console. I will write about that later. This guide is based on Ubuntu 12.04 LTS.   1. Enter your VM’s “Edit Properties” menu. Choose your hard drive and give more space as you want: 2. In the same window, click “Options” tab, choose “Boot Options” and enable “Force BIOS Setup” on the right side: 3. Click “OK”. 4. Go to g-parted web site and download the ISO file from there: http://gparted.org/ 5. Right click on your VM and click “Open Console”. Click the “Connect CDROM” button on top right and choose “Connect to ISO image on local disk”. 6. Choose your g-parted ISO file and click “OK”. 7. Now reboot your VM. You will see the BIOS screen. Go to “Boot” tab. Using UP-DOWN arrow select “CD-ROM drive” and bring it before Hard Drive using “+” sign on your keyboard. Go to Exit tab and select “Exit Saving Changes”. This will reboot your virtual machine. 8. You will see boot screen of g-parted. Click “Enter” for G-Parted Live. (You can hit Enter for default selections for 9-10-11 steps) 9. Choose “Don’t touch keymap” for Configuring console-data. 10. It will ask for language selection. Type your language number and hit Enter. Default is 33 (English). 11. Choose G-Parted mod, default is “0”. 12. G-parted will boot and Device manager screen will be shown in the screen. Now select LVM device which’s File System is “extended”. […]
