rootvg is, as the name suggests, the volume group ( vg ) that contains / ( root ) and any other logical volumes you created during installation — it’s basically the default AIX volume group. Volume Groups ( VG s) are an AIX thing — they’re basically logical disks (comprised of one or more Physical Volumes ( PV s).
How do I mirror a Rootvg?
There are four steps required in mirroring rootvg:
- Mirror rootvg using mirrorvg or mklvcopy.
- Make the new mirrored disk bootable by running bosboot.
- Add the new mirrored disk to the bootlist.
- Reboot the system to disable quorum. (5300-06 and below only)
What is Datavg?
datavg (“data volume group”) for all customer data that is separated from the operating system to allow upgrading the OS without changing the customers’ data. The LVM handles all disks of the “datavg“ volume group directly and without any traditional partition table.
What is a volume group?
A volume group is a type of storage pool that contains one or more physical volumes of varying sizes and types. A physical volume can belong to only one volume group per system. There can be up to 4096 active volume groups on the Virtual I/O Server.
What is LV in AIX?
A physical partition is the smallest unit of allocation of disk where the data is actually stored. A logical volume is a group of one or more logical partitions that can span multiple physical volumes. All the physical volumes it spans must be in the same volume group.
What is Varyonvg?
Description. The varyonvg command activates the volume group specified by the volumegroup parameter and all associated logical volumes. A volume group that is activated is available for use. When a volume group is activated, physical partitions are synchronized if they are not current.
What is VGDA and VGSA?
A quorum is a vote of the number of Volume Group Descriptor Areas and Volume Group Status Areas (VGDA/VGSA) that are active. A quorum ensures data integrity of the VGDA/VGSA areas in the event of a disk failure. Each physical disk in a volume group has at least one VGDA/VGSA.
What is LTG in AIX?
LTG is the maximum transfer size of a logical volume (volume group?). At 5.3 and 6.1 AIX dynamically sets LTG size (calculated at each volume group activation).
What is PP in AIX?
PP SIZE is set at the time of volume group creation using the ‘-s’ flag. If the PP SIZE is small and the disk is large, there could be an unmanageable number of physical partitions. For example, a 1TB disk with PP SIZE 4MB, will have 262,144 physical partitions.
What is logical volume?
Logical volume management (LVM) is a form of storage virtualization that offers system administrators a more flexible approach to managing disk storage space than traditional partitioning. This type of virtualization tool is located within the device-driver stack on the operating system.
Is AIX an operating system?
