关于orion在AIX下测试硬盘的问题

nashitian

我的mytest.lun里面只写了一个/dev/hdisk20  然后执行
#./orion_aix_ppc64 -run advanced -testname mytest -num_disks 8 -size_small 2048000 -size_large 2048000 -type rand
然后他会出现
ORION: ORacle IO Numbers -- Version 11.1.0.7.0
mytest_20110418_0630
Test will take approximately 39 minutes
Larger caches may take longer

storax_skgfr_openfiles: File identification failed on /dev/hdisk20
OER 27037: please look up error in Oracle documentation
Additional information: 5
rwbase_lio_init_luns: lun_openvols failed
rwbase_rwluns: rwbase_lio_init_luns failed
orion_thread_main: rw_luns failed
Non test error occurred
Orion exiting
请问下这些失败都是为什么啊？
