Description

Error Message

The /var/vx/vras/log directory contains log files for the vradmind server.

VxVM VVR vradmin ERROR V-5-52-82  Cannot communicate with vradmind server


The vradmin_A.log with debugging enabled would have an entry similar to what is shown below:

VxVM VVR Debug V-5-20-0 IpmHandle TAG_I Local host name (::ffff:x.x.x.x) is found in hashtable

 

Cause

This issue occurs if the nameserver entries in the /etc/resolv.conf file are not reachable.

When the "vradmin" command attempts to contact the nameserver, this can take a long time to respond. 

The Domain Name System (DNS) is the hierarchical and decentralized naming system used to identify computers reachable through the Internet or other Internet Protocol (IP) networks.

If the DNS server is not being reachable or able to respond to ping requests, then all "vradmin" commands would timeout before it can open a socket connection to the vradmind server.

 

Resolution

To address this issue, perform the below steps:


1.] Confirm that the nameserver entries defined in the /etc/resolv.conf file are not responding to a ping request by performing a "ping" test for each nameserver.


2.] Once this is confirmed. rename the /etc/resolv.conf to /etc/resolv.conf.Org


3.] Restart the vradmind server for the changes to take effect
 

For RHEL 7, SLES 12, and supported RHEL distributions:

# systemctl stop vras-vradmind

# systemctl start vras-vradmind
 

For Solaris, AIX and earlier versions of RHEL and SLES, use:

# /etc/init.d/vras-vradmind.sh stop

# /etc/init.d/vras-vradmind.sh sart
 

4.] Now attempt to run the "vradmin" command that was previously failing.

The "vradmin" command should now run successfully. Where possible correct the nameserver entries in /etc/resolv.conf.
 

Issue/Introduction


The "vradmin" utility performs administrative tasks on a Replicated Data Set (RDS) in a Veritas Volume Replicator (VVR) environment.

When attempting to run "vradmin" related commands, it fails to connect to the vradind server.
