scsi alert.


HI,

I have this following alert on one of my servers. I understood it partially but not sure if I understood it right. What does this alert mean and what do I check for it. If this is an error how do I fix it. Please help. Thanks in advance.

UNIX-LINUX PM: kernel: scsi: host 0 channel 3 id 0 lun4194304 has a LUN larger than allowed by the host adapter

I'm using RHEL6.5

Depends on your host adapter.

There are only two possibilities:

1. The LUN is corrupted.
2. The LUN was initialized outside the adapter being used to connect to it and the current adapter is more limited.

In either case, you may lose data... I would suspect the first case if the filesystem on the LUN is valid. That would mean that the LUN configuration got corrupted somewhere and needs to be repaired.

In the second case, the adapter may have been replaced due to a failure but the replacement is more limited. I kind of doubt this one as I think it would be rather unlikely to happen.

In both cases, make sure you have a backup... especially before trying to repair anything.

The following scsi errors are reported; where <xxx> is greater than lpfc module parameter lpfc_max_luns.

Was the #2 issue.

Thanks for your replies. What do I need to check and how do I check it. Can you please let me know what commands do I use to check them. FYI.. we are using native multipathing.
