AIX下如何添加磁盘，修改磁盘属性

备份当前磁盘情况
/usr/DynamicLinkManager/bin/dlnkmgr view -drv | grep """"hdisk"""" | tr ‘.‘ ‘ ‘ | awk ‘{ print $NF, $2}‘ | sort | uniq > /install/disks.before.20181115
扫盘
cfgmgr -l fcs0/1/2/3
查看确认多出来的2块盘的盘号
/usr/DynamicLinkManager/bin/dlnkmgr view -drv | grep """"hdisk"""" | tr ‘.‘ ‘ ‘ | awk ‘{ print $NF, $2}‘ | sort | uniq > /install/disks.after.20181115
cat /install/disks.after.20181115
核实lun号是否为如下：
00:25:BB
00:25:BC

2.两个节点分别对新识别出来的2块磁盘修改属性等，盘号以实际为准
chdev -l hdisk<x> -a pv=clear -a queue_depth=8 -a reserve_policy=no_reserve
chown grid:asmadmin /dev/rhdisk<x>
chmod 660 /dev/rhdisk<x>
