Hi there I want to know which is the proper manner … or essentially the most really useful technique to current the disks to ASM, for instance: I’ve three disks mapped to a server (rhel7) orasys, orafra, oradata, with dm-multipath I configure the multipath and I put aliases (orasys, orafra and oradata respectively). The doubt I’ve from there, I’ve learn within the guides, that the disks are formatted, leaving for examples: orasys1, orafra1, oradata1 and these are those which are offered to ASM as /dev/mapper/* and with the respective permissions … however after I do it that manner it offers an error ending the set up of the grid as a result of it can not create the diskgroup, nonetheless if I don’t format them, that’s, I current them instantly as orasys, orafra and oradata I’ve no downside.
The database is oracle 19c and I do not use asmlib however udev guidelines.
Thanks.
