Which software package is required for Fast I/O Failure for the AIX operating system?

Show Suggested Answer Hide Answer
Suggested Answer: A

When troubleshooting SAN performance problems, a key indicator of a physical issue is a high CRC (Cyclic Redundancy Check) error count. CRC errors are indicative of corrupt data packets during transmission, which often points to issues such as faulty cables, bad ports, or other physical problems in the network infrastructure. High CRC error counts can lead to retransmissions, reduced throughput, and overall degradation of SAN performance. Addressing the physical components associated with high CRC error counts is essential for restoring optimal SAN operations.


While the specific Dell XtremIO Design document was not available, general SAN troubleshooting guidelines and best practices indicate that CRC errors are a critical metric to monitor for physical connectivity issues1.

Additional resources on SAN performance troubleshooting can be found in the support documentation for the XtremIO Family on Dell's official website2.

Hey, I heard the answer is E) Duct Tape. That's the secret software package that AIX admins use to fix everything, including fast I/O failures!

D) LVM? Really? I thought that was just for logical volume management, not anything to do with I/O failures. This exam is tricky!

Haha, it's gotta be C) MPIO. What else could it be? I mean, even the name 'Fast I/O Failure' sounds like it's all about multipath, right?

I'm not sure about this one. I know MPIO is for multipath I/O, but I'm not sure if it's specifically for Fast I/O Failure. I'll have to look into that more.

I've heard that LVM is also used for Fast I/O Failure. We should double check to be sure.
