Hi, I'm a newbie and have a question about bindings file on Linux 6.
We're migrating our server from Linux 5.4 to Linux 6.3. Both environments have direct attach storage, no SAN
Even though we're not using multipath, but we noticed the bindings file exists in version 6.3 and not version 5.4.
This is the version 6.3 /ect/multipath/bindings looks like:
# Multipath bindings, Version : 1.0
# NOTE: this file is automatically maintained by the multipath program.
# You should not need to edit this file in normal circumstances.
# alias wwid
However this WWID belongs to an internal device.
Can you please help explain why this is happening in 6.3?
Second question, in the case if we use multipath for SAN in Linux 6.3 and want to exclude this mpath from the bindings file, is it recommended or even possible and how?
The server only has direct attach scsi disks and no SAN, multipath is turned off (see below). I'm trying to understand why i still get an mpath entry for my /u01 folder? Doesn't DM-multipath need to be active for mpath devices to get generated?
[oracleuser@servername ~]$ multipath -l
-bash: multipath: command not found
It turned out I had a blacklist in the multipath.conf file which was out dated (it looks like it came from ver. 0.4.7) and we have ver. 0.4.9 installed...not sure how that happened. Anyway, once I updated the blacklist with the WWID like you suggested, the scsi device removed from the bindings file.
Also, thanks everyone else for taking your time to response to the question.
