NAME

vxdarestore - restore simple or nopriv disk access records

SYNOPSIS

/etc/vx/bin/vxdarestore

DESCRIPTION

The vxdarestore utility is used to restore simple or nopriv disk access (da) records that have failed due to changing the naming scheme used by vxconfigd from c#t#d#s#-based to enclosure-based.

The use of vxdarestore is required if you use the vxdiskadm command to change from the c#t#d#s#-based to the enclosure-based naming scheme. As a result, some existing simple or nopriv disks go into the "error" state and the VxVM objects on those disks fail.

vxdarestore may be used to restore the disk access records that have failed. The utility also recovers the VxVM objects on the failed disk access records.


  Note    vxdarestore may only be run when vxconfigd is using the enclosure-based naming scheme.


The following sections describe how to use the vxdarestore utility under various conditions.

Simple/Nopriv Disks in the Boot Disk Group

If simple or nopriv disks in the boot disk group, bootdg, go into the "error" state, use the following procedure:

1.

Use the vxdiskadm command to change back to the c#t#d#s# based naming scheme.

2.

Either shut down and reboot the host, or run the following command:

vxconfigd -kr reset

3.

If you want to use the enclosure-based naming scheme, add a sliced disk to the bootdg disk group, use vxdiskadm to change to the enclosure-based naming scheme, and then run vxdarestore.

Simple/Nopriv Disks in Disk Groups other than the Boot Disk Group

If all disk access records in an imported disk group consist only of simple and/or nopriv disks, the disk group is put in the "online dgdisabled" state after changing to the enclosure-based naming scheme. For such disk groups, perform the following steps:

1.

Deport the disk group using the following command:

vxdg deport diskgroup

2.

Run the vxdarestore command.

3.

Re-import the disk group using the following command:

vxdg import diskgroup

NOTES

Use of the vxdarestore command is not required in the following cases:

The vxdarestore command does not handle the following cases:

EXIT CODES

A zero exit status is returned if the operation is successful or if no actions were necessary. An exit status of 1 is returned if vxdarestore is run while vxconfigd is using the c#t#d#s# naming scheme. An exit status of 2 is returned if vxconfigd is not running.
