arbitration Principles
when setting up your quorum device, follow these guidelines:
The quorum device is established between all nodes connected to the same shared disk storage group. Add a disk to the shared group as the quorum device to ensure that, in the event of any node failure, other nodes can maintain quorum and can control the group of disk devices on the shared group.
The quor

FAQs about physical isolation locks
Do physical isolation locks must adopt dedicated switch integrated circuits?
A: No. In the implementation of the switch, the most direct way is to use a dedicated switch integrated circuit to directly control the bus. Due to the horizontal limitation of China's chip manufacturing industry, it is difficult to guarantee the performance and quality. When it is sent to foreign production, it is necessary to hand over the circuit design and worry about security is

If you want to use USB bulk for transmission and want devices to communicate with PC hosts like serial communication, you usually need to build a PC-side driver, which is troublesome.
To avoid the trouble of writing a USB device driver on a PC, you can make the device into a mass storage device and use a general driver.
Before communication, the device must do two things:
1. Implement the descriptor and class request of the Mass Storage Class.
2. Implement the necessary

Multi (0) disk (0) RDISK (0) Partition (1) \ Windows = "Windows XP"
If your computer is started from a SCSI hard drive, you may need to replace multi (0) with

By default, your Linux kernel may not support SCSI devices,
Background description: In a Linux system, if you add a new SCSI disk or map a SAN storage LUN operation, a disk identifier (sd*) will appear after restarting the operating system.For example, the previously added SAN storage LUN has a disk identifier of/DEV/SDD, and after a reboot it turns out to be/DEV/SDH, especially in an Oracle RAC environment where we do not want to see this.Before you solve this problem, you need to understand the wwid and UUID
other things such as information collection, installation may be used.
The various Linux distributions now support CD-ROM booting directly, so go to your machine's CMOS settings and set the CDROM at the front of the boot sequence to view your motherboard manual to change the boot sequence. If you are using a CDROM that supports the SCSI interface for CD boot, you can also boot with SCSI. You may need to se
