Mpathadm showing no paths to 1 lun, others luns are fine
Hi,
I've noticed that mpathadm states that one of our luns has no active paths:
The same lun shows up in iostat:
And is mirror in a zpool:
If the lun had no active paths, surely zfs would have complained? I only just added this lun to the zpool recently too. Is this a reporting anomoly - or deeper issue here?

the plot thickens, after checking messages, I found the following. And the lun paths are offline/onlining constantly.
googling does not reaveal much. I'll see if I can log a case with Oracle.
Last time I had a similar issue, we fixed it by issuing a forcelip via luxadm. Some might look at it as if it was a demon but it helped me in the past.
To list the ports:
Then reinitialize the one giving you headache via -e forcelip
But be careful:
Might be worth opening a case with Oracle. Let us know what they recommend or if you give my idea a shot.
If no paths were present for device, device would be offline in format, and you would not be able to manipulate it at all. Zpool status would be degraded.
Can you show output of other working disk from that same storage using same paths via mpathadm show lu.
If it's ok for other working disk, report it.
You can try forcelip, but do it one fabric at the time, monitoring syslog for return on paths before issuing it on next.
I've logged a ticket with Oracle about this issue, and to their credit were very quick in coming back with a response. Apparently mpathadm has serveral associated bugs, and for accurate reporting, i'd be better off using:
Which indeed showed all paths online as expected. To fix mpathadm, they've suggested I apply patch
143643-08, and a series of others. But after removing disk/configuring once more, it's reporting back ok.
We are using Solaris 11 Logical Domains. We NFS share a disk backup area from one LDom to other servers. The share is on a single 1.5 Tb LUN presented to the Control Domain, and as a virtual disk on the NFS server LDom. A 1.5 Tb zpool has been created on the LDom. We now need to provide more disk...

Hello,
Looking for some guidance to changing how an AIX 6.1 server sees its luns. Presently they're connected via 1GB iscsi but I want to change it to 4GB fiber channel. Anyone done this before and if so is it an easy step?
I'm thinking this can be done in this order:

Hi,
I have a sun 440, it already has LUN's configured with MPXIO.
I just had more LUNS added, I did devfsadm and cfgadm -al, and they're showing up twice in "Format". :confused:
There are no new fiber cables or HBA's involved, same physical setup, just adding LUNS.
Aren't they... (0 Replies)
