Top Forums UNIX for Beginners Questions & Answers New to AIX: How do I setup high availability on an AIX System Post 303038834 by mathisecure on Sunday 15th of September 2019 08:28:35 AM

My apologies. I should have put more context around my question. I was trying to keep my post concise and to the point. Given your lengthy response, I will respond in kind. I am not sure where you got the idea that I am trying to cram and fake my way but I can assure you, that is absolutely not the case. My background is in Directory Servers and IAM products. My last position was administering Ubuntu and Centos systems. My entire career has been spent working in Unix environments of all flavors mostly from an application engineering perspective. The position I am interviewing for was presented to my by a recruiter, as many are, who found my resume online. There is nothing in my resume that mentions anything about administering AIX other than from working with applications on AIX systems. When contacted by the recruiter, I presented him with the facts and told him up front that I had never performed AIX administration and that my only unix admin experience was with Ubuntu and Centos systems. I was very up front with him and gave him several references who could attest to my background and work ethic. I can assure you that I am not trying to present myself as an experienced AIX admin. I am well aware of the fact that this is an impossibility. My goal is to do my research and present myself as being, at least somewhat, intelligent of the task at hand. You do mention presenting oneself with integrity which I absolutely agree with 100%. I am going into this interview with base knowledge, a strong work ethic and a desire to learn. Again, my only goal with doing research is to be able to present myself with some aspect of base intellect at the position.

To reiterate my question which really wasnt answered

is PowerHA applicable on all newer AIX systems as a tool for setting up high availability and failover or is PowerHA specific to Power systems.

I am well that this is most likely a stupid question to the firmly entrenched and highly knowledgeable but I am a firm believer of the old axiom "there are no stupid questions"

I should also mention that I do not know what systems the position will be working with which is why I am asking the question in the first place

NAME
vgexport - export an LVM volume group and its associated logical volumes SYNOPSIS
mapfile] outfile] vg_name mapfile vg_name DESCRIPTION
Using the format of the first command line of the above, the command can be used to remove a volume group from the system. The volume group will be removed without modifying the logical volume information found on the physical volumes. The volume group identified by vg_name is removed from the or file, and the associated device files including the vg_name directory and file are removed from the system. The volume group information and data is untouched on the physical volume. These disks can be imported to another system with the command (see vgimport(1M)). Scan Option Using the format of the second command line of the above, the command generates a mapfile that can be copied to other systems that are part of a high availability cluster (use the option if you do not want to remove the volume group from the system the command is being run from) and the command (see vgimport(1M)) can be used to recreate the volume group. See also vgchange(1M). The mapfile contains a description of the volume group and its associated logical volume(s) (if any). The logical volume information found on the physical volumes is not modi- fied. Options and Arguments recognizes the following options and arguments: vg_name The path name of the volume group. By default, a file named is created in the current directory. This file contains a description of the volume group and its associated logical volume(s) (if any). Use this option to specify a different name for the file, mapfile. This file can be used as input to (see vgimport(1M)). When used with the option, the volume group specified in the mapfile can be shared with other systems in the high availability cluster. Preview the actions to be taken but do not update the or file or remove the devices file. This option is best used in conjunction with the option. Print verbose messages including the names of the physical volumes associated with this volume group. Scan option. When the option is specified, then the options must also be specified. A mapfile is created that can be used to cre- ate volume group entries on other systems in the high availability cluster (with the command). Write the current set of pv_paths for the volume group to the outfile. The outfile may then be used as the infile for the option. If used together with the option the volume group is not exported but the list of pv_paths is still written to the outfile. This may be useful to derive a list of pv_paths for the volume group or to use on another system which is sharing the volume group and which has an identical configuration. EXTERNAL INFLUENCES
Environment Variables determines the language in which messages are displayed. If is not specified or is null, it defaults to "C" (see lang(5)). If any internationalization variable contains an invalid setting, all internationalization variables default to "C" (see environ(5)). EXAMPLES
Export the volume group into mapfile The volume group will be removed from the exporting system. Export the volume group and write the disk names into the file Create a mapfile to be copied to other systems in a high availability cluster to build the volume group information for the volume group, Note that the volume group is not removed from the exporting system. The importing systems will create the volume group with the command using the and options. SEE ALSO
