ASM Diskgroup Issues Standalone Server

rsar001Sep 27 2018 — edited Sep 28 2018

Hi There,

We're running Oracle 11.2.0.4 EE on Oracle Linux Server release 6.10. This is a standalone environment ASM environment:

oracle@kc1prdb02 ~]$ crsctl stat res -t

--------------------------------------------------------------------------------

NAME           TARGET  STATE        SERVER                   STATE_DETAILS

--------------------------------------------------------------------------------

Local Resources

--------------------------------------------------------------------------------

ora.DATA.dg

               ONLINE  ONLINE       cmddev01

ora.FRA.dg

               ONLINE  ONLINE       cmddev01

ora.LISTENER_ASM.lsnr

               ONLINE  ONLINE       cmddev01

ora.LISTENER_CMDDEV.lsnr

               ONLINE  ONLINE       cmddev01

ora.asm

               ONLINE  ONLINE       cmddev01                Started

ora.ons

               OFFLINE OFFLINE      cmddev01

--------------------------------------------------------------------------------

Cluster Resources

--------------------------------------------------------------------------------

ora.cssd

      1        ONLINE  ONLINE       cmddev01

ora.diskmon

      1        OFFLINE OFFLINE

ora.evmd

      1        ONLINE  ONLINE       cmddev01

We changed the host name and host ip, recycled the server, and obviously oracle has didn't come up, so we followed MOS doc id 986740.1 "How to Reconfigure Oracle Restart" to reset the environment. We removed HAS configurations, reconfigured it again, added ASM, started the ASM instance, then we proceeded to recreating the ASM pfile:

asm_diskgroups='DATA','FRA'

instance_type='asm'

large_pool_size=12M

remote_login_passwordfile='EXCLUSIVE'

Then we ran the following "crsctl stat res -t":

--------------------------------------------------------------------------------

   NAME           TARGET  STATE        SERVER                   STATE_DETAILS

   --------------------------------------------------------------------------------

   Local Resources

   --------------------------------------------------------------------------------

   ora.asm

                  ONLINE  ONLINE       cmddev03                Started

   ora.ons

                  OFFLINE OFFLINE      cmddev03

   --------------------------------------------------------------------------------

   Cluster Resources

   --------------------------------------------------------------------------------

   ora.cssd

         1        ONLINE  ONLINE       cmddev03

   ora.diskmon

         1        OFFLINE OFFLINE

   ora.evmd

         1        ONLINE  ONLINE       cmddev03

Then we logged in to the ASM instance to mount the DATA diskgroup and we're stuck:

SYS@+ASM> alter diskgroup DATA mount;

alter diskgroup DATA mount

*

ERROR at line 1:

ORA-15032: not all alterations performed

ORA-15017: diskgroup "DATA" cannot be mounted

ORA-15040: diskgroup is incomplete

We can't mount the disk group, and we're not sure how to proceed! The resource is obviously missing from crsctl output, so does it need to be added there 1st? I've also noticed the asm_diskstring is no longer set in ASM:

SYS@+ASM> show parameter disks

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

asm_diskstring                       string

and none of the directories and/or disks are available under asmcmd. How can we add the disk groups again and mount them please? Your help is highly appreciated.

Many Thanks
