ESXi – Partitions layout of system disk

20 December 2011
Comments off

Reading Time: 3 minutesIn ESXi the partitions schema is automatically defined by the installation process and there is no way to modify it (you can only choose where install the hypervisor). There is a great post from Rickard Nobel (ESXi 5 partitions) that explain the structure of the partitions, their size and their purpose. But it does not explain how to get this information. To see the partition layout in ESXi 5, the fdisk command will not work on new GTP disk (this type is used for all new disks and for disks that are extended to more […]

ESXi – Replace the vmware-cmd command

19 December 2011
Comments off

Reading Time: < 1 minuteAs you know, several commands from local CLI (via the ESXi shell or TSM technical support mode) are changed in latest version of ESXi (in the new ESXi 5 most are replaced by the new esxcli command). One command that was alredy replaced in ESXi 4.1 was the vmware-cmd command. A new vim-cmd must be used instead (as as described by William Lam in VMware vimsh and vim-cmd). The typical use of vmware-cmd command was get/change the state of a VM and register a VM. About the state of a VM, the VMware KB1014165 (Powering off […]

Installing Dell OMSA Web Server in a VM

14 December 2011
Comments off

Reading Time: 3 minutesAs written in the previous post you can install the Dell OMSA package for ESXi 5 using VUM or the command line. Finally you need a “proxy” system with the web part of the OMSA package to connect to your ESXi. Usually this can be a physical server, like the backup server (or the media server of a backup solution). But when then backup is server is virtual and no other physical server is available? First issue is than a client OS is no supported at all (I’ve tried with Windows XP, it seems to […]

Installing Dell OMSA 6.5 on ESXi 5 using CLI

13 December 2011
No comments

Reading Time: 2 minutesIn a previous post I’ve describe how install the Dell OMSA package with VUM on ESXi 5. The Dell Open Manage (OMSA) is a useful tool (of course for physical Dell’s servers) for different reasons, like for example: configure and manage the RAID controller (for standalone servers and/or for local storage) and configure the (i)DRAC without reboot the host and enter in the POST menu (or without the physical access at the front panel). I think that the VUM approach is the simple and faster way, but some days ago I’ve got a standalone server, […]

VMFS5 – Upgrading vs. Fresh Install

6 December 2011
Comments off

Reading Time: 3 minutesWith a vSphere 5 upgrade there is an important vDesign decision: if you already have some VMFS3 datastores could be better upgrade them to the new version of build new datastores directly with VMFS5? The upgrade procedure is quite fast and friendly and could be applied to a live datastore, so seems that there isn’t a big different between an upgrade or a clean format. But usually the recommendation is to re-format each LUN to VMFS-5 rather than upgrade it. This will fix a number of issues, including:

Reclaim free space in Thin Provisioned vmdk disk

5 December 2011
Comments off

Reading Time: 3 minutesOne of the “issue” with vmdk in thin format is that they start “small” and then grow when you add new data… But when you delete some data, the vmdk file size is not reduced. To be honest this issue is more related to the guest file systems that does never delete the block data, but only the metada (or some of them). Of course at guest OS level you will see the right disk usage, but this will probably not match the one that you see at VMware level (that usually will be bigger).
