Description
Error Message
VxVM vxdg ERROR V-5-1-10978 Disk group
Cause
/etc/vx/vxdmp.exclude and/or /etc/vx/vxvm.exclude are populated with incorrect entries, excluding paths that should be accessed.
For example:
# cat etc/vx/vxdmp.exclude
exclude_all 0
paths....sdae /dev/sdae
In this case, vxdnmp.exclude is preventing access to the wrong device
Resolution
Using vxdmpinq/vxscsinq to check the disk S/N and prove that hitachi_usp-v0_04a1 and sdae point to the same device
Check the /etc/vx/vxdmp.exclude and /etc/vx/vxvm.exclude: if the issue is with these files, proceed with the following steps.
1 - edit /etc/vx/vxdmp.exclude and remove all excluded paths, file must look like the following:
# cat /etc/vx/vxdmp.exclude
exclude_all 0
paths
#
controllers
#
product
#
pathgroups
#
2 - move the following files
# mv /etc/vx/disk.info /etc/vx/disk.info.old
# mv /etc/vx/array.info /etc/vx/array.info.old
3 - remove everything under the dmp tree:
# rm -rf /dev/vx/dmp/*
4 - reboot the system
If you cannot reboot, you can follow the above procedure until step 3 and then run:
4a - freeze each service group running on system
# hagrp -freeze
5 - refresh VXVM configuration:
# vxdctl enable
6 - Unfreeze each service group :
# hagrp -unfreeze
Applies To
All devices building the affected disk group are reported twice in vxdisk list.
For example:
# vxdisk -o alldgs list |grep dgko
DEVICE TYPE DISK GROUP STATUS....
hitachi_usp-v0_04a1 auto:cdsdisk - (dgko) online thinrclm <<< HERE
sdae auto:cdsdisk - (dgko) online thinrclm <<< HERE
The disk group dgko is built from a single device, but vxdisk list reports duplicate entries with a different naming scheme.
