Starting, Stopping and Aborting Veritas Tasks

When mirrors and RAID5 devices are created with Veritas Volume Manager, the volume contents need to be synchronized to an initial consistent state (e.g., parity and mirrors need to be synchronized). Veritas assigns a unique task id to each operation, and allows tasks to be monitored and displayed with the vxtask(1m) utility:

$ vxtask list
TASKID  PTID TYPE/STATE    PCT   PROGRESS
   172           ATCOPY/R 05.57% 0/209698816/11689984 PLXATT oravol04 oravol04-02 oradg

Since synchronization can be extremely I/O intensive, you might want to pause a synchronization task until a later time. This is easily accomplished by passing the task id to vxtask(1m)’s pause option:

$ vxtask pause 172
$ vxtask list
TASKID  PTID TYPE/STATE    PCT   PROGRESS
   172           ATCOPY/P 05.76% 0/209698816/12077056 PLXATT oravol04 oravol04-02 oradg

Once you are ready to resume the task, you can use vxtask(1m)’s resume option:

$ vxtask resume 172
$ vxtask list
TASKID  PTID TYPE/STATE    PCT   PROGRESS
   172           ATCOPY/R 06.02% 0/209698816/12613632 PLXATT oravol04 oravol04-02 oradg

Similarly, if you want to abort the TaskId you can do it by:

# vxtask abort <taskid>
# vxtask abort 172

This is super useful, and it looks to have caught on.

Soltuion:
To get rid of this, solution is to re-create device mapping, restart vxconfigd, initialize the device, add the disk back to the diskgroup.
# vxdisk rm NONAMEs2 (Remove the device entry in Volume Manager)
# cd /dev/vx/rdmp (Delete all files pertaining to NONAME*)
# cd /dev/vx/dmp (Delete all files pertaining to NONAME*)
# mv /etc/vx/disk.info /etc/vx/disk.info.old
# mv /etc/vx/array.info /etc/vx/array.info.old
# devfsadm -Cv
# vxddladm stop eventsource
# vxconfigd -k (This will recreate the device mapping and the disk.info file)



Remove all the disk with name NONAME
# vxdisk rm NONAMEs2

# pwd
/dev/vx/rdmp
# ls -lrt|grep -i NONAME

The output is much longer, i had shrinked the output.

After troubleshooting from vxvm end, Disk are visible now, I will be extending the FS today.
