not able to initialize the disk

[dksingh9990]

I had a disk under VxVM control. I removed it from VxVM control. Again when I added the same disk, it is not allowing me to initialize

.Also I feel, it is showing wrong multipaths in vxdisk list output.

root@dbpdadc42> vxdisksetup -i c0t500507680140533Ad8

May be this disk is still somehwhere under volume manager configuration.

Please let us know following command outputs:

vxdisk -o alldgs -e list

vxprint -qhtr

modinfo | grep -i vx

uname -a

If you are sure that it is not part of any disk group or holding any data, can you try vxdisksetup with "-if" option?

Alongwith above outputs, also mention what were the steps used to remove the disk from diskgroup configuration ?

May you can try the option -ifr (is not documented)

vxdisksetup -ir c0t500507680140533Ad8

But if this fails, the procedure to use when adding new drives appear to us all as a single disk with as many paths as there are actual discs:
 

vxdisk rm <disk> (erase the disk)

vxdmpadm exclude dmpnodename=<dmpnode_erase_disk>

vxdctl enable

We found that no reference to the new disks:
 

vxdisk list

vxdmpadm getsubpaths

We clean the system if any erroneous reference:
 

devfsadm –Cv

Include and discover new disks:
 

vxdmpadm include dmpnodename=<dmpnode_erase_disk>

vxdctl enable

There should now be well recognized all disks.

Looks like disk is in used outside VxVM.

Please share below outputs.

vxdisk -e list | grep c0t500507680140533Ad8
