configuration file so that the kernel with the HBA Card driver module is used by default when the system starts.Fortunately, HP installs the kernel by installing a script, adding grub boot entries and setting it as the default boot, all automatically completed.--------------------------------------------------------------------------------------------------------------- ---5, about LINUX does not restart the recognition of the issue.It is generally f

zoning and LUN technology can be applied to the network and its devices together with other security mechanisms. 3. Can wwn be associated with LUNs? Associating the World Common name (WWN) with a logical unit ordinal in a disk array is a way to implement data security in a SAN. Each HBA connected to the SAN in your server has a WWN. In a single disk array, yo

Host Bus Adapter-Host Bus Adapter (HBA) is a Host Bus Adapter that provides input/output (I/O) between servers and storage devices) A circuit board and/or integrated circuit adapter that processes and physically connects. Because the HBA reduces the burden on the master processor in data storage and retrieval tasks, it can improve server performance. An hba and t

Tags: Linux replace HBA card after re-scan instructionsHere's how to view the HBA card WWN number:[Email protected] ~]# Cat/sys/class/fc_host/host*/port_name0x10000090fa4849fe0x10000090fa4849ffYou can also see the WWN number under Linux.Once the WWN number is changed, the system cannot directly update the mounted back-end storage disk. To re-scan the

In the early SAN storage system, the data transfer between the server and the switch was done through optical fiber, because the server was transferring the SCSI instruction to the storage device, could not take the IP protocol of the ordinary LAN network, so it needed to use FC transport, so this SAN is called Fc-san, And later appeared with the IP protocol encapsulated SAN, can completely walk the ordinary LAN network, so called Ip-san, which is the most typical of the now popular iSCSI. Both

In Solaris, how to configure the fc hba to an Ethernet Card IPFC can easily set a fc hba to an Ethernet card, which is of great significance. In some work sites, if you need to copy a large amount of data through the network, you will often find that the speed of the Gigabit Nic is insufficient, and network aggregation cannot compensate for bandwidth insufficiency, at this time, you can make full use of the

The solutions are:1. Use MS Utility "Fcinfo.exe" (Fibre Channel information Tool (fcinfo)) to view the WWN number of the HBA card.The Fcinfo tool is installed on a Windows system that needs to view the WWN number, and then, in the Start menu, type "CMD" in "Run" and enter command-line mode, and you can see the WWN number of the host HBA by entering Fcinfo.2, after searching, find article finds

Generally, a cardNode_name and port_name are the wwn of the HBA, and their values are the same. Sp

First explain the various operating systems to boot to the DOS path: Win9x system: After the boot press F8, select the 5th entry, you can enter the system with the basic dos7.x environment. 2K/XP/2003: The system does not come with DOS, it needs a DOS boot disk or a virtual floppy drive to get the DOS environment. This article introduces 4 kinds of DOS boot disk production methods, 4 kinds of Startup
