Article Title: how to correctly view Raid information in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open-source systems. In some cases, the system is not installed on its own, and raid is not configured on its own, after logging on to the system remotely, you may not know whether the system is raid or raid-level? Therefore, I would like to briefly summarize ho

Some time ago due to some special requirements, you need to install Xen using the 2.6.39 version of the Linux kernel, and have some problems to summarize.The first step to download the kernel, www.kernel.org, I was using the rc-3 version of the kernel. Unzip, OK.Second step configuration kernel, enter the extracted kernel directory, make menuconfig into the configuration interface, specific configuration referenceHttp://wiki.xensource.com/xenwiki/XenParavirtOpsThe third step is to compile the ke

1. Introduction to device management Devices in AIX are managed hierarchically. The top layer is the function category, that is, grouping by the same basic function. For example, all the adapter cards belong to the adapter class. The next level is the function subclass, which is divided according to more specific properties, such as standard input/output adapter and micro channel adapter. Standard Input/Output adapter belongs to the class of the SiO2 function, the micro-channel adapter is a sub-

Symptom: After a windows2012 R2 failover cluster is removed, after reinstalling the system, it is found that the disk has become raw and the formatting does not complete successfully after it has been brought online.Analysis: Due to the abnormal removal of the cluster, these disks are still locked by the PR Key (SCSI-3 reservation) of the previous cluster, causing the disks to be occupied and inaccessible and formatted.Processing:The following cleanup

SCSI SCSI is short for the small computer system interface (Small Computer System Interface). It was first proposed in 1979 as an interface technology developed for minicomputers and has been widely used in minicomputers, high-end servers and normal PCs. SCSI can be divided into SCSI-1,

1. Common Storage TechnologyDas:direct attached Storage, directly attached storage, the storage device is connected directly to the server via a SCSI interface cable, and the storage device does not have any operating system. It relies on servers, where storage devices stack up hardware devices. Das can also be referred to as SAS (server attached storage, which is servers attached storage).Das has the following characteristics:1, Das device does not h

that the fiber card information is the above section, where the total need is "1077:2,432". In the system there is a file/usr/share/hwdata/pcitable, which holds all the supported and unsupported hardware information for this system. 1077 of them represent the manufacturer qlogic,2432 is the model of the card. Well, now I have a driver package, there are many modules, in the end whether the module in this package supports this card. Exactly which module supports this card? [Root@r

one. When you open a device file, the operating system knows the driver corresponding to the device. SCSI Device SCSI is a standard computer interface different from IDE. Nowadays, most flat-board scanners, CD-R recorders, MO optical transceiver and so on gradually tend to use the SCSI interface, coupled with SCSI and

Install iSCSI in CentOS 6.6 I. Introduction to ISCSI ISCSI, internet SCSI, also known as IP-SAN, is a standard developed by IETF to map SCSI data blocks into Ethernet packets. ISCSI is a TCP/IP-based protocol used to establish and manage the connection between IP storage devices, hosts and clients, and create a storage area network (SAN ). SAN makes it possible to apply the
