There is a saying on the Internet: "I often go online. How can I leave it alone ~ ". In fact, it is not difficult to learn security knowledge to access the Internet with peace of mind.
First, we need to set a secure password. What kind of password is secure? Generally, a secure password

You can view the source code, compile the program, download the program using the SAMBA tool, and write the program to dataflsh based on the previous stereotypes of our company. You can run uboot, however, after I download AT91Bootstrap1.6 from the Internet, I changed the value of SPI1 in dataflash to SP

1. Nor Flash has an independent data bus and address bus, which can be accessed randomly like Ram. Therefore, it can run programs directly on nor flash, so nor flash can be used to start, execute in place is called xip.
2. The NAND Flash adopts the I/O mode to read data. It only

The output information mainly shows the value of enclosure device ID.
Then let's look at our new hard drive ():
Megacli-pdinfo-physdrv [E0: S0]-A0 // E0 is the ID we noted down in the previous step. S0 is the disk space and starts from 0.
We can see that unconfigure good is okay. Then create R0 online:

But I already said at the beginning that the machines in the cluster have the same configuration and the deployed programs have the same rsync as before. Is the hard disk broken?
I have to check the problem with the O M personnel. The final conclusion is:
Sdb is a dual-disk RAID 1 with a RAID card of "LSI Logic/Symbios Logic SAS1068E" and no cache. Nearly 400 of IOPS has reached the hardware limit. The raid cards used by other machines are "LSI Logic/Symbios Logic
