For example, if you want to increase the size of hd6 with 3 logical partitions, you issue the following command: The commands lsvg, mkvg, chvg, extendvg, and replacepv described in the following sections support creation, extension, and maintenance of volume groups consisting of SSDs.
For example, to deactivate the network interface tr0, run the command: How do I get partition-specific information and statistics?
You can use the lquerypv command with the -M flag. How do I display virtual memory statistics? It accepts names of logical volumes, physical volumes, or volume groups as parameters. Select information in your developerWorks profile is displayed to the public, but you may edit the information at any time.
How do I know if my volume group is normal, big, or scalable?
To display the number of processors on your system, type: While the behavior of these commands should be identical in all releases of AIX, they have been only tested under AIX 5.
You use the following command to change the characteristics of a volume group: To display if the hardware is bit or bit, type: The value is 32 for normal, for big, and for scalable volume group. To view the characteristics of all workload partitions, type: You can display all logical volumes that are part of rootvg by typing the following command: To determine if IY is installed, type: How do I determine if all filesets of maintenance levels are installed on my system?
The defragfs command can be used to improve or report the status of contiguous space within a file system. The intent is to provide a list that you can use as a ready reference. The lparstat command provides a report of partition information and utilization statistics.
Type the following command: You can use the chps -s command to dynamically increase the size of a paging space. It accepts names of logical volumes, physical volumes, or volume groups as parameters.
To activate the network interface tr0, run the command: When all the physical volumes are removed from the volume group, the volume group is deleted. The following example shows how to clone the rootvg to hdisk1. The default value for scalable volume groups is the lowest value to accommodate physical partitions per physical volume.
AIX 5L Version 5. The default value for scalable volume groups is the lowest value to accommodate physical partitions per physical volume. How do I identify the network interfaces on my server?
Shiv Dutta discusses some of the AIX commands that answer those questions and tells you how to enlarge the list of such answers. Please choose a display name between characters. The value is 32 for normal, for big, and for scalable volume group. The following options provide specific information: The value is 32 for normal, for big, and for scalable volume group.
You can remove the logical volume lv7 by running the following command: Volume groups and logical volumes AIX V7. To list the current values of the attributes for the tape device, rmt0, type: If neither the -w boot or the -w now options are specified, then the mode change is made immediately.
How do I determine if a fix is installed on my system? It's 1 through for AIX 5. Your display name must be unique in the developerWorks community and should not be your email address for privacy reasons.
To find out what xx is in hdiskxx, run the following command: The default value for standard and big volume groups is the lowest value to remain within the limitation of physical partitions per physical volume.You can use the chps -d command to dynamically reduce the size of a paging space.
For example, if you want to decrease the size of hd6 with four logical partitions, you issue the following command: For example, if you want to decrease the size of hd6 with four logical partitions, you issue the following command. Do you ever feel you could save time by not having to call on the support professionals all the time?
Well, wish no more.
Shiv Dutta discusses some of the AIX commands that answer those questions and tells you how to enlarge the list of such answers. Admittedly, a list such as this can be helpful in quickly answering some of your own questions.
However, it does not cover everything that you might need. You can extend the usefulness of such a list by adding other commands that answer additional questions not addressed here.

These subsets differ from user to user and from need to need. However, there are a few core commands that you commonly.
