Rename SP in MapR

                                                 Rename SP in MapR

Sometimes for consistency Admin would want SP name to be same as the old SP name even after SP is recreated. Usually after SP is recreated it doesn't have the same original SP name .


Below are the steps to rename an SP. 

[root@node-1 ~]# /opt/mapr/server/mrconfig sp list 
ListSPs resp: status 0:2 
No. of SPs (2), totalsize 584687 MB, totalfree 583859 MB 

SP 0: name SP1, Online, size 290295 MB, free 289881 MB, path /dev/sdb 
SP 1: name SP2, Online, size 294391 MB, free 293978 MB, path /dev/sde 

[root@node-1 ~]# /opt/mapr/server/mrconfig sp offline /dev/sde 

[root@node-1 ~]# /opt/mapr/server/mrconfig sp list 
ListSPs resp: status 0:2 
No. of SPs (2), totalsize 290295 MB, totalfree 289881 MB 

SP 0: name SP1, Online, size 290295 MB, free 289881 MB, path /dev/sdb 
SP 1: name SP2, Offline, size 307197 MB, free 0 MB, path /dev/sde 

[root@qa-node-111 ~]# /opt/mapr/server/mrconfig sp rename -n SP4 /dev/sde 
SP renamed to SP4 

[root@node-1 ~]# /opt/mapr/server/mrconfig sp online /dev/sde 

[root@node-1 ~]# /opt/mapr/server/mrconfig sp list 
ListSPs resp: status 0:2 
No. of SPs (2), totalsize 584687 MB, totalfree 583859 MB 

SP 0: name SP1, Online, size 290295 MB, free 289881 MB, path /dev/sdb 
SP 1: name SP4, Online, size 294391 MB, free 293977 MB, path /dev/sde 

Now SP2 is rename to SP4 as needed.
