今天在公司做了下试验,重温了一下Vxvm单机下在线更换根盘的方法,希望能帮到有需要的朋友,现在贴出来和大家分享,转贴请注明出处,谢谢!
环境: 硬件:1×E450(3×36GB disk) 软件:Solaris 9,Vxvm 3.5
1.由于我的环境中的根盘是好的,可能会与实际环境不同,在这里特别指出,但是方法一样!
- root@sun # vxdisk list
- DEVICE TYPE DISK GROUP STATUS
- c0t0d0s2 sliced rootdisk rootdg online(实际中此个盘坏了,报failed)
- c0t1d0s2 sliced rootmirr rootdg online
复制代码
- root@sun # format
- Searching for disks...done
- AVAILABLE DISK SELECTIONS:
- 0. c0t0d0 (这个是正常状态,坏盘后可能会有出入)
- /pci@1f,4000/scsi@3/sd@0,0
- 1. c0t1d0
- /pci@1f,4000/scsi@3/sd@1,0
- Specify disk (enter its number): ^D
复制代码
- root@sun # vxprint -ht
- Disk group: rootdg
- DG NAME NCONFIG NLOG MINORS GROUP-ID
- DM NAME DEVICE TYPE PRIVLEN PUBLEN STATE

- v rootvol - ENABLED ACTIVE 20480121 ROUND - root
- pl rootvol-01 rootvol ENABLED ACTIVE 20480121 CONCAT - RW

复制代码
2.运行vxdiskadm命令,将坏了的根盘从vxvm里面REMOVE掉:
- root@sun # vxdiskadm

- q Exit from menus
- Select an operation to perform: 4
- Remove a disk for replacement
- Menu: VolumeManager/Disk/RemoveForReplace
- Use this menu operation to remove a physical disk from a disk
- group, while retaining the disk name. This changes the state
- for the disk name to a "removed" disk. If there are any
- initialized disks that are not part of a disk group, you will be
- given the option of using one of these disks as a replacement.
- Enter disk name [,list,q,?] list
- Disk group: rootdg
- DM NAME DEVICE TYPE PRIVLEN PUBLEN STATE
- dm rootdisk c0t0d0s2 sliced 2888 71124291 -

- Enter disk name [,list,q,?] rootdisk
- The following volumes will lose mirrors as a result of this
- operation:
- rootvol swapvol
- No data on these volumes will be lost.
- The requested operation is to remove disk rootdisk from disk group
- rootdg. The disk name will be kept, along with any volumes using
- the disk, allowing replacement of the disk.
- Select "Replace a failed or removed disk" from the main menu
- when you wish to replace the disk.
- Continue with operation? [y,n,q,?] (default: y) y
- Removal of disk rootdisk completed successfully.
- Remove another disk? [y,n,q,?] (default: n) n

3.查看一下状态:
- root@sun # vxdisk list
- DEVICE TYPE DISK GROUP STATUS
- c0t1d0s2 sliced rootmirr rootdg online
- - - rootdisk rootdg removed was:c0t0d0s2
- root@sun # vxprint -ht
- Disk group: rootdg
- DG NAME NCONFIG NLOG MINORS GROUP-ID
- DM NAME DEVICE TYPE PRIVLEN PUBLEN STATE
- RV NAME RLINK_CNT KSTATE STATE PRIMARY DATAVOLS SRL
- RL NAME RVG KSTATE STATE REM_HOST REM_DG REM_RLNK
- V NAME RVG KSTATE STATE LENGTH READPOL PREFPLEX UTYPE

- c0::dsk/c0t1d0 disk connected configured unknown

- c1::dsk/c1t6d0 CD-ROM connected configured unknown
复制代码
4.在此需要修改一下dump设备路径,将dump设备路径指向mirror盘,不然从设备树中删除根盘的时候会有问题:
- root@sun # cfgadm -c unconfigure c0::dsk/c0t0d0
- cfgadm: 部分系统忙,重试: 脱机失败:
- Resource Information
- ------------------ -----------------------
- /dev/dsk/c0t0d0s1 dump device (dedicated)
复制代码
- root@sun # dumpadm
- Dump content: kernel pages
- Dump device: /dev/dsk/c0t0d0s1 (dedicated)
- Savecore directory: /var/crash/sun
- Savecore enabled: 是
- root@sun # dumpadm -d /dev/dsk/c0t1d0s1
- Dump content: kernel pages
- Dump device: /dev/dsk/c0t1d0s1 (dedicated)
- Savecore directory: /var/crash/sun
- Savecore enabled: 是
复制代码
- root@sun # cfgadm -al
- Ap_Id Type Receptacle Occupant Condition
- c0 scsi-bus connected configured unknown
- c0::dsk/c0t0d0 disk connected unconfigured unknown
- c0::dsk/c0t1d0 disk connected configured unknown
- c1 scsi-bus connected configured unknown
- c1::dsk/c1t6d0 CD-ROM connected configured unknown
- root@sun # cfgadm -c unconfigure c0::dsk/c0t0d0
复制代码
5.带好防静电手套,更换根盘; 6.重配根盘;
- root@sun # cfgadm -c configure c0::dsk/c0t0d0
- root@sun # cfgadm -al
- Ap_Id Type Receptacle Occupant Condition
- c0 scsi-bus connected configured unknown
- c0::dsk/c0t0d0 disk connected configured unknown
- c0::dsk/c0t1d0 disk connected configured unknown
- c1 scsi-bus connected configured unknown
- c1::dsk/c1t6d0 CD-ROM connected configured unknown
复制代码

8.查看同步状态;

- sd rootmirr-01 swapvol-02 rootmirr 0 4191939 0 c0t1d0 ENA
复制代码
10.将dump设备换回到根盘上:
- root@sun # dumpadm -d /dev/dsk/c0t0d0s1
- Dump content: kernel pages
- Dump device: /dev/dsk/c0t0d0s1 (swap)
- Savecore directory: /var/crash/sun
- Savecore enabled: 是
复制代码
如果卷状态如上说明换盘成功! 有时实际和我的环境还是有很大出入的,可能用vxdiskadm选4选5换不了,或是换了以后同步有问题等等,欢迎大家拍砖。。。。。
