The WordPress.com stats helper monkeys prepared a 2012 annual report for this blog.

Here’s an excerpt:

19,000 people fit into the new Barclays Center to see Jay-Z perform. This blog was viewed about 65,000 times in 2012. If it were a concert at the Barclays Center, it would take about 3 sold-out performances for that many people to see it.

In tape library as well there was an amber light showing. Tried to re run the backup, did a inventory, rebooted the tape library, nothing worked. But when i login to the tape library GUI console through IE could see that below error.

This labeled tape removed from library and re run the backup job. Starts working fine.

Hyper-V and VHD’s

VHD’s provide storage for virtual machines and are stored on physical media as .VHD files.

While creating a new virtual machine we can create VHD’s or can select existing VHD’s which we already created or used. Or we can add a VHD later and can complete the VM creation wizard.

OK. Now i want to give  an additional drive or partition to this VM.

1) Create a VHD from hyper-v console.

2)Attach that VHD from Hyper-V snap-in of VM as additional hard disk from IDE controller 0 or add as second IDE controller, Then add hard drive. ( snapshot below)

3) Or we can add additional SCSI controller from hyper-v settings if IDE controller 0 and 1 are fully used. To do this click add hardware and select SCSI controller

4)Once you add you can see physical disk option. Select disk from drop down list ( this disk should be offline in disk management of hyper-v host server. Other wise we cannot see the disk in this console)

These are the two method we can assign disks to VM’ from hyper-v console of the Hyper-v server. To add any hardware VM must be shutdown. Or from SAN you can directly map the hard disks in to VM’s by using iSCSI initiator in windows.

Adding VHD’s as additional hard disks ( IDE controller)
