Introduction to File system operations and Disk Management experimentsThe file system operation of this section of the experiment is very simple and contains only a few parameters of several commands, but mastering these will also help you in the process of learning about other courses in Linux and the lab building. Because this course is positioned as a primer, as soon as possible, so there is no

SCVMM R2 Operations Management 11: Adding hyper-V clustersThe previous blog post and everyone described how to add a trusted Hyper-V host and a non-trusted Hyper-V host. But we need to know that in many cases we already have Hyper-V's high-availability environment before we go to SCVMM, so today we're going to introduce you like and add the existing Hyper-V cluster in our environment to SCVMM.Since some of

SCVMM R2 Operations Management 13: Adding resources to the VMM libraryThe previous blog post tells you how to add a library server to VMM, and in today's post you'll discuss how to add resources to the VMM library for our use.We can use the following procedure to add a file's resource (also known as a physical resource) to an existing library share in System Center 2012–virtual machine Manager (VMM), and th

The following operations are based on p4v. 1 P4 refresh all In some cases, some modifications cannot be updated in p4v in real time. In this case, p4v refresh all can be used. You can also right-click any item to find refresh-related operations. For example, if you delete or add files in the local directory, the file cannot be reflected in p4v in time. You can right-click the refresh option in the w
