Description
Error Message
'vxdg adddisk' commands fails with the following error messages.
VxVM vxdg ERROR V-5-1-639 Failed to obtain locks: emcpower61s2: no such object in the configuration
Resolution
Disks which have been removed accidentally do not physically exist. Here is the example to illustrate this:
# vxdisk -o alldgs list
The above 2 disks (emcpower61s2 and emcpower62s2) which have been shown as '
If the physical disks exist and are ready to be replaced or added back to the diskgroup, those disks should be listed or shown as follow:
# vxdisk -o alldgs list
Ensure that the operating system recognizes those physical devices, through 'format' command. If the operating system can access those devices in question, so can the volume manager and they will be listed in the "vxdisk -o alldgs list" output.
The operation to put the disks back into the diskgroup fails if the underlying devices do not exist.
The following need to be done to ensure the disks are visible through the operating system first:
1. Through 'format' or 'fdisk' command and make sure that the disks are listed and visible through the operating system.
2.The VTOC or label is valid and readable.
Once the devices exist and are visible to the operating system, please ensure volume manager also sees them. To do this,we need to allow the volume manager to rescan all of the devices again (through 'vxdctl enable' command) and ensure the devices are listed through 'vxdisk -o alldgs list' command.
Once the devices are visible through volume manager, the following command can be executed to add the disk back into the Diskgroup :
# vxdg -g -k adddisk
# vxdisk -o alldgs list

Once the devices are visible through volume manager, the following command can be executed to add the disk back into the Diskgroup :
# vxdg -g
If the -k option is specified, the disk media name must represent a disk media record that was previously dissociated from its disk access record with -k rmdisk; otherwise, a new disk media record is created to represent the disk. With the -k option, plexes requiring recovery are flagged as stale.
For example, for the above scenario, the following command adds one of the failed disk back into the diskgroup.
#vxdg -g t3dg01 -k adddisk lun-1da6=emcpower61s2
For example, for the above scenario, the following command adds one of the failed disk back into the diskgroup.
#vxdg -g t3dg01 -k adddisk lun-1da6=emcpower61s2
