Backup and recovery is what system administrators often do, including ROOTVG backups and user data backups. 1. Backup of operating system and System program: Insert a new tape or unwanted tape into the tape drive #tctl-F/dev/rmt0 Rewind #smit MKSYSB Add "/dev/rmt0" to the backup device or file, and then enter. The system will run for a long time until the screen is OK to take out the tape. At this point, the system backup is complete. Attention:

Generally, in the production environment, most of my rootvg is mirror. if the ML upgrade fails or some operation is incorrect, it will take me to restore the rootvg, whether it's using tape mksysb recovery or network boot recovery... when will the cloning technology be used!

This article provides two interesting scenarios that I have encountered and steps for detecting exceptions. Then stop, let you guess what went wrong, and finally give the answer. Example First, describe the two problems I encountered as a system administrator. Problem 1: the server is larger, but the com

Some peripherals on the small machine, such as the host machine and the optical drive, are rarely used at ordinary times, so most of them are shared among the LPAR of a small machine. These IO devices can only be exclusively occupied by one LPAR when used between different LPAR, so they must be switched when necessary.The customer's p6 570 server has four lpars, and two of them need to be backed up using tapes. Therefore, the dynamic switching of the tape drive between the two lpars is involved.

It is best to use several tape copies in turn. The backup tape must indicate the backup time and content. 1) log on with the root user 2) mount the file system to be backed up under rootvg 3) Smit mksysb Select backup media Change expand/tmp filesystem if needed to Yes

environment for the workloads running in the WPAR. To easily migrate the AIX V5.2 workloads running on older hardware to POWER7 hardware, you only need to create the mksysb image of the AIX V5.2 system. Then, the image is provided when WPAR is created on AIX V7.1 running on POWER7 hardware. In addition, LAM supports transferring AIX V5.2 WPAR between POWER7 systems running AIX V7.1. LAM requires the purchase of IBM PowerVM™Workload Partitions Manager

Problem 1: the server is larger, but the computing power is reduced. At that time, I needed to extract an AIX5.3LPAR from a POWER4-based? Old IBMpSeries? P670 server migration to POWER6-based? PSeriesp570 server. The old server resources are insufficient (using WorkloadManager to manage the resources of main applications on the server). Therefore, the new dynamic processor resources on the new hardware should provide the computing power I need. I performed m
