To clean up the system configuration
# vxdisk list
This displays a list of system disk devices and the status of these devices. For example, for a reinstalled system with three disks and a reinstalled root disk, the output of the vxdisk list command is similar to this:
DEVICE TYPE DISK GROUP STATUS sdb simple - - error sdc simple disk02 bootdg online sdd simple disk03 bootdg online - - disk01 bootdg failed was:sdb
The display shows that the reinstalled root device, sdb, is not associated with a VM disk and is marked with a status of error. The disks disk02 and disk03 were not involved in the reinstallation and are recognized by VxVM and associated with their devices (sdc and sdd). The former disk01, which was the VM disk associated with the replaced disk device, is no longer associated with the device (sdb).
If other disks (with volumes or mirrors on them) had been removed or replaced during reinstallation, those disks would also have a disk device listed in error state and a VM disk listed as not associated with a device.
# vxprint -sF "%vname" -e 'sd_disk = "disk"'
where disk is the name of a disk with a failed status. Be sure to enclose the disk name in quotes in the command. Otherwise, the command returns an error message. The vxprint command returns a list of volumes that have mirrors on the failed disk. Repeat this command for every disk with a failed status.
# vxprint -th volume
where volume is the name of the volume to be examined. The vxprint command displays the status of the volume, its plexes, and the portions of disks that make up those plexes. For example, a volume named v01 with only one plex resides on the reinstalled disk named disk01. The vxprint -th v01 command produces the following output:
V NAME USETYPE KSTATE STATE LENGTH READPOL PREFPLEX PL NAME VOLUME KSTATE STATE LENGTH LAYOUT NCOL/WID MODE SD NAME PLEX DISK DISKOFFS LENGTH [COL/]OFF DEVICE MODE v v01 fsgen DISABLED ACTIVE 24000 SELECT - pl v01-01 v01 DISABLED NODEVICE 24000 CONCAT - RW sd disk01-06 v0101 disk01 245759 24000 0 sdg ENA
The only plex of the volume is shown in the line beginning with pl. The STATE field for the plex named v01-01 is NODEVICE. The plex has space on a disk that has been replaced, removed, or reinstalled. The plex is no longer valid and must be removed.
# vxedit -r rm v01
V NAME USETYPE KSTATE STATE LENGTH READPOL PREFPLEX PL NAME VOLUME KSTATE STATE LENGTH LAYOUT NCOL/WID MODE SD NAME PLEX DISK DISKOFFS LENGTH [COL/]OFF DEVICE MODE v v02 fsgen DISABLED ACTIVE 30720 SELECT v02-01 pl v02-01 v02 DISABLED NODEVICE 30720 STRIPE 3/128 RW sd disk02-02v02-01 disk01 424144 10240 0/0 sdi ENA sd disk01-05v02-01 disk01 620544 10240 1/0 sdj DIS sd disk03-01v02-01 disk03 620544 10240 2/0 sdk ENA
The display shows three disks, across which the plex v02-01 is striped (the lines starting with sd represent the stripes). One of the stripe areas is located on a failed disk. This disk is no longer valid, so the plex named v02-01 has a state of NODEVICE. Since this is the only plex of the volume, the volume is invalid and must be removed. If a copy of v02 exists on the backup media, it can be restored later. Keep a record of the volume name and length of any volume you intend to restore from backup.
# vxedit -r rm v02
If hot-relocation is disabled, you can recover the mirror manually. In this example, the vxprint -th command for a volume with one plex on a failed disk (disk01) and another plex on a valid disk (disk02) produces the following output:
V NAME USETYPE KSTATE STATE LENGTH READPOL PREFPLEX PL NAME VOLUME KSTATE STATE LENGTH LAYOUT NCOL/WID MODE SD NAME PLEX DISK DISKOFFS LENGTH [COL/]OFF DEVICE MODE v v03 fsgen DISABLED ACTIVE 0720 SELECT - pl v03-01 v03 DISABLED ACTIVE 30720 CONCAT - RW sd disk02-01 v03-01 disk01 620544 30720 0 sdl ENA pl v03-02 v03 DISABLED NODEVICE 30720 CONCAT - RW sd disk01-04 v03-02 disk03 262144 30720 0 sdm DIS
This volume has two plexes, v03-01 and v03-02. The first plex (v03-01) does not use any space on the invalid disk, so it can still be used. The second plex (v03-02) uses space on invalid disk disk01 and has a state of NODEVICE. Plex v03-02 must be removed. However, the volume still has one valid plex containing valid data. If the volume needs to be mirrored, another plex can be added later. Note the name of the volume to create another plex later.
