Hi,

I think that is solved this way

1-Add OB2IPCKEEPALIVE=1 on omnirc file

2-Increasing the TCP/IP retransmission time decreases the possibility of a network problem due to network congestion or other issues.   The recommended value is 8, maximum value can be 12.  This is done by adding a registry value (use regedit.exe):

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\TcpMaxDataRetransmissions

Data=0x00000008 (This should be of type DWORD)

Set this value on all Windows systems that experience this problem.   A reboot is required for the setting to take affect. 

 

I hope this can help you

Hi Eblyn,

CM + MA are linux servers. Trouble is 30 second between abort and start new ma process. The reason - unavailable path to the drive or outage on SAN. I need suppress the time.

[Normal] From: BMA-NDMP@dpmam1 "HP:Ultrium 6-SCSI_16_dpmam1" Time: 1/20/2021 12:52:15 PM
ABORTED Media Agent "HP:Ultrium 6-SCSI_16_dpmam1"

[Normal] From: BMA-NDMP@dpmam1 "HP:Ultrium 6-SCSI_1_dpmam1" Time: 1/20/2021 12:52:46 PM
STARTING Media Agent "HP:Ultrium 6-SCSI_1_dpcmam1

In omnirc are some parameters where I can increase timing. This is working if I disabled port on SAN media agent, 2-5sec. But if  SAN drive on tape library is down (error on FC ports drive, or unavailable port on tape drive, still I have 30s.
