Re: status of the lun presented
As i can see total 8 paths are present and 4 is active and 4 is standby, beacuse in EVA there are 2 controllers and one should be active and another should be standby (it is for redundancy purpose). There for you can see only 4 paths will be in actice mode, if it failed then the stanby status will change to active.
I think everything clear now. Please let me know if have any issues.
Regards,
Prasanth Thomas.

Re: status of the lun presented
Please send me the output of the below command. Is this LUN is a part of any VG ?
And only disk513 is having the issue or all the LUNs have the issue.
scsimgr get_info -D /dev/rdisk/disk513.
Regards,
Prasanth Thomas.
