Lspci # to see if there is a HBA,linux6 that can be viewed through lspci

First confirm what kind of optical fiber card it is:

Lspci | grep-I fibre

Basically, there are two types of optical fiber cards:

Emulex: lsmod | grep lpfc

Qlogic: lsmod | grep qla

Lsmod # View the information of loaded driver modules

If FC HBA loads the correct driver, there is a lot of information about HBA under / sys/class/fc_host/hostx

# # replace HBA card #

The way to check the HBA card WWN number is as follows:

[root@361way ~] # cat / sys/class/fc_host/host*/port_name

0x10000090fa4849fe

0x10000090fa4849ff

You can also see the wwn section under linux.

After changing the WWN number, the system cannot directly update the mounted backend storage disk. If you need to re-scan the next disk, you can use the following methods to do so:

# cd / sys/class/scsi_host/host4/

# echo'-'> scan

Or

Echo "1" > / sys/class/fc_host/host/issue_lip / / some storage or systems do not have scan files, which can be identified by issue_lip files

Note:

You can run fdisk-l before scanning and compare the results of fdisk-l after scanning. If the replacement is successful, you will find that the latter will see more results than the former. Therefore, before this kind of operation, it is best to make a backup of df, fdisk, mount, fstab and other information related to the disk. After the scan is completed, it is the safest to make a comparison with the original data.

It doesn't matter if you can't remember the scan instructions above, the same effect can be achieved by rebooting the host.

Before and after the disk sweep, you can confirm the storage mount information by viewing / proc/scsi/scsi

[root@361way ~] # cat / proc/scsi/scsi

# # add HBA card #

The installation sequence of the HBA card and the operating system determines the operation steps of the host external storage. If HBA is installed before the operating system, it is relatively easy to connect to the disk. Setup detects the discovered hardware and prepares the required modules. If the adapter is installed after the operating system, or if it changes after the operating system installation, the user needs to install it manually. This article uses Emulex 1000 as an example HBA.

HBA is installed before the operating system: the installer discovers the hardware and prepares the module

HBA installed or changed after the operating system: manually installed by the user

Add HBA card to HP DL380
