Today, I will talk to you about how to add a hard disk in Linux. Many people may not know much about it. In order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

1. After adding the disk, it was not refreshed.

[root@node /] # fdisk-l

Disk / dev/sda: 17.2 GB, 17179869184 bytes

255 heads, 63 sectors/track, 2088 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x000aa84a

Device Boot Start End Blocks Id System

/ dev/sda1 * 1 2089 16775168 83 linux

/ dev/sda2 2089 2089 1024 82 Linux swap / Solaris

two。 View host bus number

Root@node /] # ls / sys/class/scsi_host/

Host0 host1 host2

3. Rescan the SCSI bus to add devices

[root@node /] # echo "- -" > / sys/class/scsi_host/host0/scan

[root@node /] # echo "- -" > / sys/class/scsi_host/host1/scan

[root@node /] # echo "- -" > / sys/class/scsi_host/host2/scan

4. Looking at the disk, you can see / dev/sdb: 53.7g this is the newly added disk.

[root@node /] # fdisk-l

Disk / dev/sda: 17.2 GB, 17179869184 bytes

255 heads, 63 sectors/track, 2088 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x000aa84a

Device Boot Start End Blocks Id System

/ dev/sda1 * 1 2089 16775168 83 Linux

/ dev/sda2 2089 2089 1024 82 Linux swap / Solaris

Disk / dev/sdb: 53.7 GB, 53687091200 bytes

255 heads, 63 sectors/track, 6527 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00000000
