If you’ve ever asked yourself “what is SMS mode in AIX?” and have been unsure how to access it, you have come to the right place. It’s an option on AIX systems that allows you to see the addresses of the SCSI controllers attached to your system. It can be used to make Fs, but be aware that the LPAR will always boot to the SMS menu.
LPAR always boots to the SMS menu
In AIX 5.3 TL9SP1, my LPAR always boots to the SMS menu. However, I can boot from my SAS drive in SMS. Is there a way to fix this problem? This article will give you an answer. Depending on the microcode level of your disk, you might need to change the boot list in SMS to select the desired disk. Then, re-boot your AIX system.
To boot from SMS menu in AIX, first you must disable LPAR. If you are using the standalone version, restart AIX. Once you restart AIX, you will see a normal bootlist. To verify whether or not your LPAR is booting from SMS menu, use the command lspv to show the disks and lpa. You should see hd5 boot on the list.
It could allow a malicious user to boot the system
A rootkit is a type of malicious software that is silently installed by users when they install software. For example, Sony secretly bundled a rootkit with their Extended Copy Protection software that came with millions of Sony CDs. The rootkit modified the host operating system so that users were unable to make copies of the CDs. This rootkit was exploited by hackers. So, how do you prevent rootkits from booting your system?
The vulnerability is in the GRUB2 configuration file. An attacker can exploit it to override signature verification and install malicious bootloaders. Malicious bootloaders can be installed on a computer even when Secure Boot is enabled, giving an attacker complete control of the device. To avoid being compromised by a malicious user, you should actively manage the dbx database. There are many ways to protect your system from malicious bootloaders.
It allows you to view the addresses of the SCSI controllers attached to your system
The first step in viewing the addresses of the SCSI devices connected to your system is to locate the SCSI device on the list. The disk with the address 1 will be connected to the SCSI controller 0, while the DAT tape and CD drive will be connected to the SCSI controller 1. To assign a different SCSI device to each controller, press the space bar to open the device properties window.
You can also click on the ‘Configure’ option to see the settings of your SCSI adapter. By default, SCSI parity checking and termination are enabled. To configure your startable device parameters, click on the ‘Boot Device Configuration’ option. You may also want to check the ‘SCSI Parameters’ option and select the device ID.
It allows you to make Fs on AIX
The linux toolkit for AIX adds a number of open source utilities to the system, including the rpm package manager. However, the linux toolkit is stuck in 2002, which means that many of the newer Linux updates are missing from this version. It also lacks rpmbuild, which has been replaced by rpm –recompile. And unlike Linux, there is no automatic patch to update the source code, making development on AIX extremely painful.
There are a variety of AIX file systems. Journaled file systems use database journaling techniques to ensure structural consistency. Each file system contains a root directory and subdirectories. The /etc/filesystems file is a central repository for information about the file system and is used by most AIX maintenance commands. Hence, there is no need to perform a new configuration for every device.
