Registering Linux host using Navisphere Host Agent
On EMC KB site i found few articles which I compiled togather the information togather for my future references
If a Host shows up as unmanaged/unreachable in Navisphere.Or the Host does not register with the fully qualified host name and IP address, then you can follow these steps to fix the issue:
First step you need to Verify if port 6389 is open. Navisphere Host Agent uses the /etc/hostfile on a Linux host to create the HostIDFile.txt file. Navisphere uses the HostIDFile.txt file to register the host. In order for the host to register and show up as being managed the /etc/hostfile should contain the fully qualified host name and the IP address MUST be included in the hostfile.
Hostfile example:
# Do not remove the following line, or various programs# that require network functionality will fail.127.0.0.1 localhost.localdomain localhost10.21.41.61 testvmesx1.test.com.au testvmesx1
If there are multiple entries, comment out all but the entries that you want the host to register to the CLARiiON with. (Once the host registers, the user can then uncomment the entries in the /etc/hostfile.) Once the appropriate changes have been made, cd into the /var/log directory. Locate HostIDFile.txt and delete it. Stop and start the Navisphere Host Agent.
Once the host Agent starts, a new HostIDFile.txt will be created. From Navisphere Manager, right-click the array and click Update Now. Then under the hosts tab, right-click the host, select Properties, and verify that next to Operating System the Agent is reporting the correct operating system.

How to stop and start Navisphere Agent on various OS
Logon to Service Console
From VMware:
/etc/init.d/naviagent stop
/etc/init.d/naviagent start
From Linux environment:
/etc/init.d/naviagent stop
/etc/init.d/naviagent start
From Novell NetWare:
load sys:\emc\agent\navagent -f sys:\emc\agent\agent.cfg
unload navagent
From Windows:
Go to "Services" (Click on Start ---> Run -----> services.msc), ENTER
Click STOP SERVICE,and then click START SERVICE ( or simply click the RESTART SERVICE).
From VMware:
/etc/init.d/naviagent stop
/etc/init.d/naviagent start
From Linux environment:
/etc/init.d/naviagent stop
/etc/init.d/naviagent start

Registering HBAs With the Storage System
The process of Registering Fibre Channel HBAs or iSCSI with the storage system enables the storage system to see the HBAs or NICs. To register HBAs with the storage system, require you to start or restart the Navisphere Agent on the host.
VMware server ESX 2.5 and above
For example:
Logon to Service Console with sufficient privileges and initiate the following command:
# /etc/init.d/agent stop
# /etc/init.d/agent start
VMware server ESX 2.5 and above
For example:
Logon to Service Console with sufficient privileges and initiate the following command:
# /etc/init.d/agent stop
# /etc/init.d/agent start

ESX Host Not Responding
In some instances when I login to VC and I find a particular ESX host status is displayed “host not responding”. This is something in most cases can be resolved by restarting the vpxa and the mgmt services by executing the following commands at Services Console:
Service vmware-vpxa restart
Service mgmt-vmware restart
Service vmware-vpxa restart
Service mgmt-vmware restart

Setting Up Your First Domain Controller With Windows Server 2008
I found this really good web site and all the credits goes to ElMajdal. This is something that I'll be looking to perform in next few months . Our Domain functional level is Window 2000 native but since I decommissioned the last domain controller (Windows 2000), which was also running MS Exchange 2000 on it. Now that we upgraded our mail server to Microsoft Exchange 2007 CCR and there are no Windows 2000 domain controllers.
I'll be migrating from Windows 2003 to Windows Server 2008 and transfering the FSMO roles to Windows Server 2008.

I found ElMajdal's website very informative and posted the details on my blog for my future references:

Unable to access a file since it is locked
Just before our Data Centre move, I consolidated most of our servers using virtualization technology, using P2V most of our servers were virtualised successfully. Except during this process I experienced 1 or 2 servers having a lock file issues.
When I started the VM on the ESX host and got an error message of: “Unable to access a file since it is locked”. After some investigation on the VMware community forums and so on, I found two solutions and I wanted to post them on my blog for my own future reference but also for all you out there for whom it might be helpful to.
All the credits go to Rob Bohmann & ctfoster for their contributions:
