NEW QUESTION 21
An administrator finds that their development server has crashed and an error code 554 is displayed. They know that this error is typically associated with a problem executing varyon rootvg and they should boot from AIX Media to be able to perform maintenance tasks. When the administrator checks the crontab of the NIM server, they find that a mksysb image is created each night.
Can the administrator use this mlcsysb to boot the server and perform the required maintenance tasks?
- A. No, because mksysb is not bootable.
- B. Yes, but they may need to create a spot first.
- C. Yes, but they may need to create a machine resource first.
- D. No, because they need to use the original AIX installation media for that server.
Answer: C
Explanation:
A mksysb image is a snapshot of the AIX operating system and its configuration, so it can be used to boot the server and perform the required maintenance tasks. However, in order to use the mksysb image, the administrator may need to create a machine resource in the NIM environment first. According to the IBM AIX v7 Administrator Specialty Study Guide (page 13-6), the mksysb image should be used in combination with a previously created machine resource, which defines the parameters for the installation.
NEW QUESTION 22
A SAN administrator increased the size of a LUN device (hdisk) that is being used by a AIX LPAR. However, the system administrator does not see the new size using the lsvg or Ispv commands.
Which command updates the system with the new size?
- A. cfgmgr
- B. extendpv
- C. chvg -g
- D. synclvodm
Answer: A
Explanation:
The cfgmgr command updates the system configuration database with the current configuration of the devices attached to the system. When the SAN administrator increases the size of a LUN device (hdisk), it is not automatically reflected on the AIX LPAR. Running the cfgmgr command updates the system with the new size information and makes it visible to the system administrator.
