Hi

We are still in the initial stage of CRS (Oracle's Cluster Ready Services) installation on Sun Cluster 3.1. Immediately after about 12 minutes of CRS is installed, one node reboots on its own and later when this node comes up, another node reboots. This process goes on until we stop the CRS services manually.

The CSSD logfile shows following error for this cause:

[ CSSD]2005-12-22 11:32:50.701 [9] >TRACE: clssgmClientConnectMsg: Connect from con(100ae2900) proc(100ae3690) pid() proto(10:2:1:1)
[ CSSD]2005-12-22 11:33:19.236 [7] >WARNING: clssnmDiskPMT: long disk latency (595006 ms) to voting disk (0//devcrsvd/voting/voting.dbf)
[ CSSD]2005-12-22 11:33:21.246 [7] >ERROR: clssnmDiskPMT: 1 of 1 voting disks unavailable (0/0/1)[ CSSD]2005-12-22 11:33:21.246 [7] >TRACE: clssscctx: dump of 0x100272550, len 3792

As you can see it says voting disk is unavailable. This voting disk is created by Oracle CRS itself. But for some reason it is not able to communicate with this file/disk after the installation.

Please note that we are using Oracle 10g R2 (10.2.0.1) on Sun SPARC 9 with Sun Cluster 3.1. We are using QFS 4.4 storage.Any ideas why this error is caused?
