rdsk vs dsk creation of LUN in OC

edited Aug 21, 2017 9:42AM in Ops Center (MOSC) 4 commentsAnswered

Noticing some discrepancies when presenting backend devices to LDOMs.

Some LDOMs are created with VDSDEV using block devices others as raw.  Why?

Which device is preferred for Oracle RAC raw or block?

Also, when presenting to LDOM, should I present raw or block?

Why does OC choose /dev/dsk on some occasion and /dev/rdsk on others?

Is there a way to make all the backend devices consistently /dev/rdsk?

sample output of ldm ls -o disk primary where 1 disk is rdsk while two others are dsk ...

    primary-vds0

Howdy, Stranger!
