Veritas Volume Manager 5.1 SP1 Administrator"s Guide (5900-1506, April 2011)

At the following prompt, indicate whether you want to enable another device

(y) or return to the vxdiskadm main menu (n):

Enable another device? [y,n,q,?] (default: n)

After using the vxdiskadm command to replace one or more failed disks in a

VxVM cluster, run the following command on all the cluster nodes:

# vxdctl enable

Then run the following command on the master node:

# vxreattach -r accesname

where accessname is the disk access name (such as c0t1d0). This initiates the

recovery of all the volumes on the disks. Alternatively, halt the cluster, reboot

all the cluster nodes, and restart the cluster. If you do not perform this step

for a cluster, the nodes may not be able to see the disks, and the error Device

path not valid will be displayed.

Taking a disk offline

There are instances when you must take a disk offline. If a disk is corrupted, you

must disable the disk before removing it. You must also disable a disk before

moving the physical disk device to another location to be connected to another

system.

Warning: Taking a disk offline is only useful on systems that support hot-swap

removal and insertion of disks. If a system does not support hot-swap removal

and insertion of disks, you must shut down the system.

To take a disk offline

Select Disable (offline) a disk device from the vxdiskadm main menu.

At the following prompt, enter the address of the disk you want to disable:

Select a disk device to disable [<address>,list,q,?]

c0t2d0

The vxdiskadm program disables the specified disk.

At the following prompt, indicate whether you want to disable another device

(y) or return to the vxdiskadm main menu (n):

Disable another device? [y,n,q,?] (default: n)
