putty server unexpectedly closed network

So we have unplugged the power cable from failue path and made the server up from redundant path, but still server is in abnormal behaviour. The power supply in slot B is not receiving adequate AC power. (4) i have executed the event monitoring cmd as we are facing this problem frequently and in irregular interval of time. Root is not mirrored one and we don't have alternate boot path. (3)I have also tried the RS to reset the RST signal but during boot process it is not giving me primary boot path and giving the INIT= -7 error ( boot failure error) but after hard reboot, server detect the primary boot path. (2) when server was hung, i have generated the TC but it is not giving me proper booting response also dump not generated in /var/adm/crash. (1) I have checked the kernel parameter with # kmtune -q npty/nstrtel, it is giving default value 60. ( and let me know if any additional information, if require.) (6) As it is Live server, users are getting affected so Kindly suggest to rectify the issue. (5) But this is 3Rd time in row we are facing the same problem, I have checked the syslog but unable to find the cause of this. (4)This is 3rd time we are facing same issue, First time we have Hard Rebooted the server physically.Ģnd time I have reset the RST signal using “RS”.Īfter Rebooting server in both of the case I am able to login the server using putty (ssh). (3) I have tried with GSP prompt and I am getting the GSP prompt butĪfter selecting “CO” option it is not giving me CON SOLE LOGIN.

(2)Also we are getting the Monitoring alert as “SERVER - ssh DOWN” for same server.īut one interesting thing is SERVER is PINGING but we are not able login the server. (1) We are getting the error of “server unexpectedly closed network connection” while login remote server through putty (But I am able to connect the other server on same N/W using same putty.) Also users are not able to access the sap application.

Need your valuable suggestion for the following scenario:. I am facing one serious problem with hp-ux server 11.23, PA-RISC system having sap application on it. HPE Blog, Austria, Germany & Switzerland.
