Maybe the connections were coming and going. I'd open a support case to verify.

Its a two node cluster and happened with only one node

What does syslog show during the issue timeframe ? What is Veritas Version and Linux version here ?

Not sure where did you see both the paths are disabled. The vxdisk list output shows that paths are

enabled. Config copy disabled is not an issue since there are other disks in same diskgroup which will have Enabled config copy.

Please open support case.

Yes,  both the paths are showing as enabled but both are showing as secondary.

Ideally one path shows as primary and other secondary as ita an A/P  array.

 

how can I enable the config in one disk ?

Enabling config copy is not going to change anything. We need to find out why it is showing as secondary for both the paths. Please open support case.

Hi,

 

I know about support case .I have asked for help if someone can suggest me.

Please donot  reply  with same line . It will discourage other helpers too.

Unfortunately, The information you have posted is not useful to unerstand the issue and suggest any concrete step to resolve the issue.

I am sorry if my information is not correct.

I want to know why dmp is showing both the paths as secondary when both the paths are enabled

What could we check  further. ?

In what circumstances , it behaves as such.

 

 

There are no messages in messages file related to scsi/disks

There are a couple of thing you can do.

they are listed below

 

1. Run rpm -aq | grep -i vxvm

2. vxdmpadm listctlr all

3. grep -i error /etc/vx/dmpevent.log | grep 2017

4. rm /dev/vx/(r)dmp/*

5. vxconfigd -k

6. vxdmpadm getsubpaths

 

if you still do not see any primary paths, check the enc clariion settings
