HP Data Protector - [61:12500] cannot connect to inet for getting file system list on host

February 23, 2016

cannot connect to inet for getting file system list on host


Sample Error Log :
[Critical] From: BSM@cellsrv01.in.com "backup_spec_01” Time: 8/16/2014
[61:12500] cannot connect to inet for getting file system list on host" winclnt01.in.com".


Reason may Caused by:

Host may be down or Data protector client services (Inet) down.



Resolution :

Troubleshooting steps for Windows clients are as follows:

1. Check if the client (i.e. winclnt01.in.com in above error) is pinging from the cell manager, if not check the issue with platform team.

2. If the server is pinging, telnet the client using port 5555 
#Telnet <Client name> 5555(eg: #telnet 5555 cellsrv01.in.com)

3. If the telnet failed, login to the windows client and check whether “Data protector Inet” service is running or not. If not start the “Data Protector Inet” service, Just by right clicking the service and restart it.

4. If the Data protector service is not listed in the “services.msc”, the DP agent might be removed from the client. Push the DP agents on this client from cell server.

5. If the telnet failed using port 5555 even data protector service running, check with platform team to open the port.



Troubleshooting steps for UNIX clients are as follows:

1. Follow the steps 1 and 2 as explained above.

2. If the telnet failed, login to the UNIX client and check for the Omni entries in /etc/services and /etc/inetd.conf using the commands below. If not found, DP client needs to be reinstalled.

[root@unxclnt01:/root]

# egrep omni /etc/services

omni 5555/tcp # DATA-PROTECTOR

[root@unxclnt01:/root]

# egrep omni /etc/inetd.conf

omni stream tcp nowait root /opt/omni/lbin/inet inet -log /var/opt/omni//log/inet.log

3. Check if the port 5555 is listening using the command below. If not, raise a request to platform team to enable the port and start the inetd daemon.

[root@unxclnt01:/root] # netstat -an | grep 5555

tcp 0 0 *.5555 *.* LISTEN

4. Check if the ‘inetd’ daemon is running, if not start it using the below commands:

[root@unxclnt01:/root] # ps -ef | grep inetd

root 2144 1 0 Aug 10 ? 7:20 /usr/sbin/inetd

# /etc/inetd –s


Follow above steps to Solve iNet issue easily .. Good Day..:)






HP Data Protector - TSM Insufficient system resources exist to complete the requested service

February 23, 2016
TSM Insufficient system resources exist to complete the requested service


Sample Error Log :
ANS9999E ntrc.cpp(928): Received Win32 RC 1450 (0x000005aa) from FileRead(): ReadFile '\\xxxx\. Error description: Insufficient system resources exist to complete the requested service.


Solution:

>> Edit the dsm.opt file by adding the param "MEMORYEFFICIENTBACKUP YES".
>> Save it.
>> Try a manual backup and check if the backup completes.

If not, this error needs attention from platform end.

>> Windows OS has the paging file space memory that needs attention.
>> Issue can be resolved by adding/modifying "PoolUsageMaximum & PagedPoolSize" in registry

For more info, please refer the article from microsoft.

Your backup should be successful, once this is fixed.

Hp Data Protector - [81:52] Not a valid mount point => aborting [Solved]

February 23, 2016


Hp Data Protector


Sample Error Log :

[Critical] From: VBDA@winsrv01 "winsrv01 [/F]" Time: 5/26/2014 9:28:58 AM
[81:52] /F
Not a valid mount point => aborting.


An attempt to backup the specific drive (F:/ in this example) connected to the DP client machine was failed and no data will be backed up by DP.


Solution :

In Windows :
Login to the windows client machine and check if the drive is accessible.
Check if the drive is local drive or zoned drive and the zoning still exists.

In case the zoned drive no more exists, you can exclude it in the backup spec.

If the drive exists on the server and it is accessible, try deleting files under the \tmp folder on the windows client machine and rerun the backup.

Default path to tmp folder for windows 2003/NT/XP:
C:\Program Files\OmniBack\tmp

Default path to tmp for windows 2008:
"C:\ProgramData\Omniback\tmp"

What was causing this??
Is there any transactions happening in these DBs or not??
Any patching on server or DB that prevents the data transfer??
Why DP doesn't err anything??


No idea until we checked the seaudit log.
The inet service was restarted from an local admin account, from then onwards the DP processes were lacking the root access rights which prevented from reading the data.

Solution:


Once again the inet daemon was restarted from root.

Commands to restart the DP inet service from Linux client:

#/etc/init.d/omni stop
#/etc/init.d/omni start
