Lets say you want to migrate your system to a new hard drive.
Of course the best practice is to buy a hard drive with the exact same size. This will save you problems.
I think instead of changing the files where disk UUIDs reside just swap UUIDs between the old and new disk.
invalid partition -- table wrong signature 0
This means something went wrong with the partition table and you want to use fdisk to write a valid partition table.
There is an extensive discussion about benefits and disadvantages of this features.
I have decided to disable it.
1. open “/etc/sysconfig/prelink” in a text editir (such as vi)
2. you should see this line: PRELINKING=yes
3. change ‘yes’ to ‘no’
4. save the change you just made & exit the text editor
5. manually run “/etc/cron.daily/prelink” as root.
6. prelinking is now disabled and will not reactivate the next time you reboot.
Unfortunately this dangerous ransomware has reappeared on the network and managed to inflict heavy damages to business across the Europe especially Spain and then UK.
Bad guys have figured out how to effectively penetrate antispam and antivirus scanning gateways including Symantec.cloud.
Someone has bought the source code and released upgraded malware collecting ransom from desperate businesses.
Read about THIS serious security enhancement in my opinion. Usually as we know local Administrators are left orphaned with weak passwords which then can compromise relatively healthy domain environment.
I have just checked a detailed benchmark of my hard drive and the information is breaking my heart. I think I have to look for some upgrade.
These disks will save reputation of Microsoft because performance of Windows systems on traditional hard drives is bad. It happens to me to turn on this system from time to time and experience the difference.
This has to do with all sorts of backup tape drives (HP, IBM) including external ones that are not supported by VMware, but you still want to make use of them on one of your VMs.
Follow THIS article and bear in mind that you will have to restart the hypervisor once then destination VM another time.
This guide is a bit messy, but will prove to be useful as I went through all the fires of Exchange migration:
Install SP3 on the current 2007 Exchange server
Get-ExchangeServer | Format-Table Name, *Version*
Very important to double check that SP3 is in place
if the version does not equal 8.3.083.6 it is not SP3
Perform Health Check of AD and Exchange by running BPA for SBS 2008
Run a full backup overnight on the Exchange server
To be honest with SP1 there was no updates to Exchange at the time I was doing the migration
Upgrade the schema on SBS Server 2008 to support Windows 2012.
Join the new SERVER to domain
Install Exchange 2013 SP1 Continue reading Exchange: 2007 SP3 to 2013 SP1 migration
Very useful during the migration, but make sure you turn it off afterwards.
Circular logging is a method of conserving hard disk space in the Microsoft Exchange transactional logging process. It works by overwriting individual log files to keep the transactional log (the set of all log files) from expanding without limit on the hard disk.

This is the right way of installing SQL server otherwise it will fail as in my case.
Solution: When the pinentry window appears, open KeePass, right click on the entry and select “Perform Auto-Type”.
Yes, HP has configured the wizard to switch the browser to full screen mode as soon as possible, but I have managed to spot that it is Firefox. HP server firmware update runs from some live DVD based on Red Hat.
