RHCL做oracle服务，现在出出阵列丢失？

Question

硬件：dell 6650两台，阵列：dell 220s　阵列用scsi线连在两台6650上，心跳线用交叉网线连两台6650上
软件：redhat AS3 u3 ,clumanager-1.2.3-1,rehdat-config-cluster-1.0.0.-5，oracle：9204

之前系统一直正常运行，最近总出问题，查message

标红一句，一进程有问题，不知是什么问题，

还有查过以前的NNTP的帖子，日志是第一句Jun 25 04:03:01 db2 syslogd 1.4.1: restart.
没明白什么意思，是说有问题吗，在重起吗？
我的日志每到一定时间就会重新生一个message，message1，messag2，messag3，message4
下面是message4

hi,

1. dell 220s 确认过支持linux和linux集群么? ( a. linux support ?; b. multi-initiator?)
2. 盘阵的lun和ACL配置正确了么?
3. 服务器和服务器的HBA配置都正确了么?
4. fencing 配置了?
5. RHELv3和Oracle9204都update到最新了么?
6. 不启oracle服务，仅仅起cluster service, 然后做一些量大点的IO操作(用orion或者script?), 盘阵正常么?
7. 柜子重新mount上后，文件系统损坏了么?文件系统出现异常了么?
