Re: Missing links in LVM
Anyway, it sounds like a Hardware problem to me.
- are you able to perform a "diskinfo /dev/rdsk/c2t1d1"?
- is the disk still visible in ioscan -fn?

Re: Missing links in LVM
However, in this case since you seem to indicate that the device in question is merely an alternate path to an active disk that is not having any problems. If this is the case, then I would have to agree with previous response that it appears to be a problem with the Interface card (SCSI or otherwise) or the cable.

Re: Missing links in LVM
Output from ioscan -fn seems to be OK.
The command diskinfo gives an normal output.
In addition there are other devices connected to the same SCSI-controller that are working properly.

Re: Missing links in LVM
The error indicates that one of the controllers in your EMC box is not working.
AS each EMC BOX will have tow controllers, one will be primary and onother is secondary. These two are redundent, if primary fails secondary will take the charge. As each disk in side the box will be monitored by both controllers, each device will have two paths (device files) to your machine.
Now it looks that the primary path to the disk is faild and secondary is become active, so you are not experiencing any problem is using the disk.
You have to replace the primary controller if all the disks are giving same message which are in side the box.
