Renaming zpool.

Few days back I came to know on "How to rename zpool" One of my UNIX Guru Alex educated me on this.

Alex I would like to say million of thanks to you for your valuable guidance.

All right, so here I am creating a zpool named “oracle-db-zp00”

# zpool create oracle-db-zp00 c8t60050768018A8023B800000000000013d0

# zpool status -v
pool: oracle-db-zp00
state: ONLINE
scrub: none requested
config:

NAME STATE READ WRITE CKSUM
oracle-db-zp00 ONLINE 0 0 0
c8t60050768018A8023B800000000000013d0 ONLINE 0 0 0

errors: No known data errors

Here I messed up with zpool name; it should be “Oracle-Apps-zp00” as per standards. To fix this mistake, I first exported the pool

# zpool export oracle-db-zp00

What zpool export does?

Export a pool from the system for importing on another system. Now at this step “zpool status –v” should not give any O/P for “oracle-db-zp00” zpool.

Now I am importing it with correct name –

# zpool import oracle-db-zp00 Oracle-Apps-zp00

# zpool status -v
pool: Oracle-Apps-zp00
state: ONLINE
scrub: none requested
config:

NAME STATE READ WRITE CKSUM
Oracle-Apps-zp00 ONLINE 0 0 0
c8t60050768018A8023B800000000000013d0 ONLINE 0 0 0

errors: No known data errors

Cool... Isn’t it easy?
