CVU主要提供了基于阶段stage的验证和基于组件comp的验证.它在安装盘中,$GRID_HOME/bin和$ORACLE_HOME/bin下都存在.
1.基于阶段stage的验证提供对某个阶段安装之前pre或安装之后post的验证.并且11g可以使用-fixup参数,生成相应的修正脚本.
cluvfy stage -list
USAGE:
cluvfy stage {-pre|-post} [-verbose]
Valid Stages are:
-pre cfs : pre-check for CFS setup
-pre crsinst : pre-check for CRS installation
-pre acfscfg : pre-check for ACFS Configuration.
-pre dbinst : pre-check for database installation
-pre dbcfg : pre-check for database configuration
-pre hacfg : pre-check for HA configuration
-pre nodeadd : pre-check for node addition.
-post hwos : post-check for hardware and operating system
-post cfs : post-check for CFS setup
-post crsinst : post-check for CRS installation
-post acfscfg : post-check for ACFS Configuration.
-post hacfg : post-check for HA configuration
-post nodeadd : post-check for node addition.
-post nodedel : post-check for node deletion.
2.基于组件comp的验证可用于对集群组件的可用性,完整性,活跃程度,健全性等进行验证,帮助了解集群状态及异常检测.
cluvfy comp -list
USAGE:
cluvfy comp [-verbose]
Valid Components are:
nodereach : checks reachability between nodes
nodecon : checks node connectivity
cfs : checks CFS integrity
ssa : checks shared storage accessibility
space : checks space availability
sys : checks minimum system requirements
clu : checks cluster integrity
clumgr : checks cluster manager integrity
ocr : checks OCR integrity
olr : checks OLR integrity
ha : checks HA integrity
freespace : checks free space in CRS Home
crs : checks CRS integrity
nodeapp : checks node applications existence
admprv : checks administrative privileges
peer : compares properties with peers
software : checks software distribution
acfs : checks ACFS integrity
asm : checks ASM integrity
gpnp : checks GPnP integrity
gns : checks GNS integrity
scan : checks SCAN configuration
ohasd : checks OHASD integrity
clocksync : checks Clock Synchronization
vdisk : checks Voting Disk configuration and UDEV settings
healthcheck : checks mandatory requirements and/or best practice recommendations
dhcp : checks DHCP configuration
dns : checks DNS configuration
