how to get asm logs in RHEL


Hi Team,
We are using oracle ASM cluster. As per the request we have deleted some disks from ASM configuration. Is there any way for getting LUN ids of these disks, so that we can remove these LUNS from storage as well.

I only knew i have removed 17 luns from ASM configuration. I forget to take the LUN ids of these LUNs. From that storage total 39 LUNs are assigned to this server, now i want to find out the LUNs which i removed from ASM.

Could you please help me out.

Regards

You're using Oracle ASM cluster on RHEL...so you're paying for support from both Red Hat and Oracle...calling them is the best thing you can do to get immediate help.

Your system logs are kept in /var/log...you may want to look through them to see if there's any mention of the devices, and you may also want to look at dmesg, providing those things haven't aged out by now. Also...you've removed the disks from ASM; have you looked at what's remaining, and what LUN's they're attached to?? That would tell you what LUN's are being used, and the ones that are 'extra' would be the ones that are unattached.
