ASM磁盘组中如何进行口令文件的拷贝

Let's use pwcopy command to copy the password file from primary asm to local file system on primary site. For example,

ASMCMD> pwget --asm
+DGP_01/ASM/PASSWORD/pwdasm.256.844043619
ASMCMD> ls +DGP_01/ASM/PASSWORD/pwdasm.256.844043619
pwdasm.256.844043619
ASMCMD> pwcopy --asm +DGP_01/ASM/PASSWORD/pwdasm.256.844043619 /tmp/pwdasm_bk
copying +DGP_01/ASM/PASSWORD/pwdasm.256.844043619 -> /tmp/pwdasm_bk
ASMCMD> pwget --asm
/tmp/pwdasm_bk
ASMCMD> pwset --asm +DGP_01/ASM/PASSWORD/pwdasm.256.844043619
ASMCMD> pwget --asm
+DGP_01/ASM/PASSWORD/pwdasm.256.844043619
