Be Friend With awk/sed | ASM Mapping

Filed under: 12c,ASM,awk_sed_grep — mdinh @ 5:10 pm

I had request to add disks to ASM Disk Group without any further details for what new disks were added.

Need to figure out which disks are on ASM now, which disks should be used as new ones.

Got lazy and created scripts for this for future use.

[root@racnode-dc1-1 ~]# /etc/init.d/oracleasm scandisks

--- [8,49] is major,minor for device
[oracle@racnode-dc1-1 ~]$ oracleasm querydisk -d DATA01
Disk "DATA01" is a valid ASM disk on device [8,49]

--- Extract major,minor for devide
[oracle@racnode-dc1-1 ~]$ oracleasm querydisk -d DATA01|awk '{print $NF}'
[8,49]

--- Remove [] brackets

[8,49
[oracle@racnode-dc1-1 ~]$ oracleasm querydisk -d DATA01|awk '{print $NF}'|sed s'/.$//'|sed '1s/^.//'

--- Alternative option to remove []
[oracle@racnode-dc1-1 ~]$ oracleasm querydisk -d DATA01|awk '{print $NF}'|sed 's/[][]//g'

More Fun With sed

Filed under: awk_sed_grep — mdinh @ 2:33 am

Objective is to convert what looks to be Samba share from Windows to Linux current directory path.

Basically, the core of the code using sed.
