ASMLib and undiscovered disks

Filed under: ASM, Tips — coskan @ 1:03 pm

I won’t give any detailed information but just a quick tip for users who are struggling with discovery of disks they mounted by ASM Lib

If you follow the steps as Tim Halls article ASM using ASMLib and Raw Devices normally everthing should go fine,  but somehow,  if your disks are not discovered, you can first follow very well written ASMLib  troubleshooting guide of Jason Arneil.

If checks are ok,  but disks are still not discovered

you should first try to put ORCL:* (Thanks Saurabh- see the comment) to your ASM disk discovery path

Still doesnt work,   like it did not in my case ?

Try this magical discovery path

/dev/oracleasm/disks/*

If you are lucky as me it will work like charm.
