Phenomenon:

A scheduled weekend maintenance, a XX business system, OS version redhat 6.x, can not start, the error is as follows:

Kernel panic - not syncing:Attempted to kill init! Pid: 1, comm: init Not tainted..

One point mentioned here is that some server staff thought it was a storage problem and wanted to throw the pot away, saying whether this string of 0C74Bxxxx numbers is the WWN number of the optical fiber card, if there is something wrong with your storage, you should have the judgment and quality of the storage professionals. Don't be neglected. At first glance, it is not. There are mainly two kinds of optical fiber card industry, one is qlogic, and the other is Emulex, which is called E card and Q Card. Anyone who has done storage operation and maintenance or implementation knows that the wwn of qlogic card and Emulex card usually starts at 21XX or 10XX, firmly throw the pan in the first second. If you don't believe it, go to the data center and have a look. You may have no HBA card to connect to the storage. You can install 13 in this place...

Solution:

still see the Echo: Kernel panic - not syncing:Attempted to kill init! Pid: 1, comm: init Not tainted...

Isn't it obvious that the kernel has crashed?

At this time, the server administrator and the business are discussing whether to reinstall it or not. This time, let's install 13 for the storage Staff. Don't worry, du Niang will search to see if it is necessary to reinstall it and find a way.

On the GRUB guide interface, select the second item and press the e key to enter the editing State. At the end, append... = 0, press enter to return, and press the B key to continue to start the system.

Select the second item and press the e key to enter the editing status.

Append **= 0 at the end, press enter to return, press B to continue to start the system.

Summary:

to do storage, you must have a wide range of knowledge. You must know a little about hosts, networks, storage, operating systems, databases, virtualization, and so on.
