Disk io error at oracle end (RAC) and getting lost device id at syslog and dmesg

Hi All,

 

Its regarding the oracle team facing some disk io errors on their RAC and on the same time i can below errors in dmesg and syslog.

This is an BL870c i2 server.

 

Mar 27 08:00:19 urrtw41 vmunix: fclp driver at 1/0/0/7/0/0/0 (/dev/fclp2) : has lost a device with id 0x32b700, PWWN 0x50060e801534c10e.


Mar 27 08:00:19 urrtw41 vmunix: This device has disappeared from the Name Server

Mar 27 08:00:19 urrtw41 vmunix: database, LUNs behind this port will not be seen.

Mar 27 08:00:29 urrtw41 vmunix: class : tgtpath, instance 45

Mar 27 08:00:29 urrtw41 vmunix: Target path (class=tgtpath, instance=45) has gone offline. The target path h/w path is 1/0/0/7/0/0/0.0x50060e801534c10e

Mar 27 08:00:29 urrtw41 vmunix:
Mar 27 08:00:32 urrtw41 CIM Indication[2368]: Indication (default format):ProviderName = HPUXFCLPIndicationProvider, PerceivedSeverity = 7, EventID = 55

Mar 27 08:00:39 urrtw41 vmunix: Target path (class=tgtpath, instance=45) has gone online. The target path h/w path is 1/0/0/7/0/0/0.0x50060e801534c10e

Mar 27 08:01:38 urrtw41 inetd[8978]: registrar/tcp: Connection from urrtw41 (10.231.167.111) at Wed Mar 27 08:01:38 2013

Mar 27 08:00:39 urrtw41 vmunix: class : tgtpath, instance 45
 

 

And again we had got the same issue but with the different path

Mar 28 16:16:50 urrtw41 vmunix: fclp driver at 1/0/0/7/0/0/1 (/dev/fclp3) : has lost a device with id 0x3cb700, PWWN 0x50060e801534c11e.


Mar 28 16:16:50 urrtw41 vmunix: This device has disappeared from the Name Server

Mar 28 16:16:50 urrtw41 vmunix: database, LUNs behind this port will not be seen.

Mar 28 16:17:01 urrtw41 vmunix: class : tgtpath, instance 46

Mar 28 16:17:01 urrtw41 vmunix: Target path (class=tgtpath, instance=46) has gone offline. The target path h/w path is 1/0/0/7/0/0/1.0x50060e801534c11e

Mar 28 16:17:01 urrtw41 vmunix:

Mar 28 16:17:11 urrtw41 vmunix: Target path (class=tgtpath, instance=46) has gone online. The target path h/w path is 1/0/0/7/0/0/1.0x50060e801534c11e

Mar 28 16:17:11 urrtw41 vmunix: class : tgtpath, instance 46

Mar 28 16:17:11 urrtw41 vmunix:

Re: Disk io error at oracle end (RAC) and getting lost device id at syslog and dmesg

What kind of storage are you using?

Looks like you loose connectivity in both SANs.

Hope this helps!
