Have you seen this yet?
Drive bypass events are situations which cause the ESH to bypass a drive port thus making it inaccessible by the host and isolating the drive from the loop. There are primarily two different kinds of drive Bypass Events:
Hope it helps
We have one case in netapp for disk failure(or disk went offline).In that case log ,I came across the word disk bypass.so i used it as disk bypass.Is it right to use?
What is the solution for drive bypass?
It can (and will) also happen if you put a disk that only supports 2gbit FC (for example a 10k RPM, or an older 15k RPM disk) into an ESH4 shelf on a 4gbit loop.
I just had a situation where a disk was bypassed. "DISK_FAIL - Bypassed by ESH" "Bypassed due to the drive self bypass".
We didn't get any information when checking FAS> aggr status -f. There were no broken disks. The autosupport did show disks on position 11 and 13 but not 12.
We didn't actively do anything to fix this, approx one hour from failure the disk got inserted into the system by itself.
Not sure if this was a Threshold Bypasses?
Couldn't be the Policy Bypass, because we didn't do anything of the following "...it will remain bypassed until manually cleared by removing and reseating the drive, or by power cycling of the shelf."
