By mistake some non-alphanumeric characters (such as control and escaped characters) were entered while adding a disk to the disk group. This is what was entered:
# vxdg -g oradg adddisk oracle^H^H?1=c1t13d0s2
# vxdisk list | grep c1t13d0
c1t13d0s2 sliced orac?1 oradg online
When trying to rename this disk, it errors out.
# vxedit -g oradg rename orac?1 oracle06
vxvm:vxedit: ERROR: Failed to obtain locks:
orac?1: no such object in the configuration
Solution:
To find out what escaped characters have been entered, do the following:
# vxdisk list | cat -v
c1t13d0s2 sliced oracle^H^H?1 oradg online
where "^H" is the control character for the
# vxedit -g oradg rename "oracle^H^H?1" oracle06
#vxdisk list | grep c1t13d0s2
c1t13d0s2 sliced oracle06 oradg online
An alternative method is to use a script. For example,
dm=`vxdisk list | grep c1t13d0s3 | awk '{ print $3 }'`
vxedit -g oradg rename $dm oracle06
