1，检查磁盘名称：
powermt display dev=all
2，修改磁盘名称方法：renamepseudo
powermap renamepseudo -s emcpowerd -t emcpowerda
powermap renamepseudo -s emcpowere -t emcpowerdb
powermap renamepseudo -s emcpowerf -t emcpowerdc
powermap renamepseudo -s emcpowerg -t emcpowerdd
powermap renamepseudo -s emcpowerh -t emcpowerde
powermap renamepseudo -s emcpowerj -t emcpowerdf
powermap renamepseudo -s emcpowerk -t emcpowerdg
powermap renamepseudo -s emcpowerl -t emcpowerdh
powermap renamepseudo -s emcpowerm -t emcpowerdi
powermap renamepseudo -s emcpowern -t emcpowerdj
powermap renamepseudo -s emcpowero -t emcpowerdk
powermap renamepseudo -s emcpowerp -t emcpowerdl
powermap renamepseudo -s emcpowerq -t emcpowerdm
powermap renamepseudo -s emcpowerr -t emcpowerdn
powermt save
3，执行磁盘配置导出和导入在其它主机：
powermap export_mappings -f 02.bak
powermap import_mappings -f 02.bak
powermt save
4，UDEV规则生成:
for i in `cat d.txt`; do echo "KERNEL==\"emcpower*\", SUBSYSTEM==\"block\", PROGRAM==\"/lib/udev/scsi_id -g -u -d /dev/\$name\", RESULT==\"$(/lib/udev/scsi_id -g -u -d /dev/$i)\", OWNER=\"grid\", GROUP=\"asmadmin\", MODE=\"0660\""; done >> /etc/udev/rules.d/99-oracle-asmdisks.rules
