linux 硬盤無法識別怎么辦?

Linux 添加新硬盤無法識別[無需重啟]的解決方法

1、查看硬盤

[root@linux-host1?~]#?lsblk? NAME????????????MAJ:MIN?RM?SIZE?RO?TYPE?MOUNTPOINT sda???????????????8:0????0??20G??0?disk? ├─sda1????????????8:1????0???1G??0?part?/boot └─sda2????????????8:2????0??19G??0?part? ??├─centos-root?253:0????0??17G??0?lvm??/ ??└─centos-swap?253:1????0???2G??0?lvm??[SWAP] sr0??????????????11:0????1???1G??0?rom? #?沒有檢查到sdb的硬盤

2、查看當(dāng)前系統(tǒng)有多少個(gè)host目錄

[root@linux-host1?~]#?ls?/sys/class/scsi_host/?-l total?0 lrwxrwxrwx.?1?root?root?0?Sep?16?12:42?host0?->?../../devices/pci0000:00/0000:00:10.0/host0/scsi_host/host0 lrwxrwxrwx.?1?root?root?0?Sep?16?12:42?host1?->?../../devices/pci0000:00/0000:00:07.1/ata1/host1/scsi_host/host1 lrwxrwxrwx.?1?root?root?0?Sep?16?12:42?host2?->?../../devices/pci0000:00/0000:00:07.1/ata2/host2/scsi_host/host2

3、有多少個(gè)host就往多少個(gè)host目錄里面文件scan追加”- – -“

[root@linux-host1?~]#?echo?"-?-?-">?/sys/class/scsi_host/host0/scan???? [root@linux-host1?~]#?echo?"-?-?-">?/sys/class/scsi_host/host1/scan?? [root@linux-host1?~]#?echo?"-?-?-">?/sys/class/scsi_host/host2/scan

4、再次檢查硬盤是否已經(jīng)識別到

[root@linux-host1?~]#?lsblk? NAME????????????MAJ:MIN?RM?SIZE?RO?TYPE?MOUNTPOINT sda???????????????8:0????0??20G??0?disk? ├─sda1????????????8:1????0???1G??0?part?/boot └─sda2????????????8:2????0??19G??0?part? ??├─centos-root?253:0????0??17G??0?lvm??/ ??└─centos-swap?253:1????0???2G??0?lvm??[SWAP] sdb???????????????8:16???0??20G??0?disk?<p>5、一鍵執(zhí)行的shell腳本</p><pre class="brush:php;toolbar:false">#!/bin/bash scsisum=`ls?-l?/sys/class/scsi_host/host*|wc?-l` for?((i=0;i?/sys/class/scsi_host/host${i}/scan done
