Hi there,
We are running multiple PE2950 servers across two independent MD3000i's (Both on the latest Gen 2 Firmware, 07.35.22.61) - 3 x PE2950's connected to one MD3000i and another 3 x PE2950's connected to another MD3000i (the configuration of each cluster is best outlined by http://www.delltechcenter.com/page/VMware+ESX+4.0+and+PowerVault+MD3000i) . These servers are running ESX 4.0 Build 175625. I am seeing the attached error in the /var/log/vmkernel log on each of the ESX servers (across both clusters): Aug 17 12:59:28 esx vmkernel: 4:02:19:17.233 cpu7:4103)NMP: nmp_CompleteCommandForPath: Command 0x12 (0x4100020d4ac0) to NMP device "mpx.vmhba32:C0:T0:L0" failed on physical path "vmhba32:C0:T0:L0" H:0x0 D:0x2 P:0x0 Valid sense data: 0x5 0x24 0x0. I am able to force these errors to occur when I manually force a rescan the iSCSI targets from the ESX VC-Client, but these errors also occur every so often. I would like to check if these errors are a problem. At present our ESX cluster appears to be running correctly, however, I would like to check these problems, and check if anyone with a similar setup has these problems. I've investigated the problem and found the following VMWare Knowledge base article: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=289902 But am unable to correctly decipher the Sense Data correctly, and it's not exactly giving much information as to if the problem is normal or not. If anyone has any ideas, your help is very much appreciated. Thanks in advance. Regards, Gene Tang
