Error: Path Bus 3073 Tgt 5006048452A6BC89 Lun 28 to 000290102002 is dead.

do you have other systems using that FA report the same error ?

No, only for one server getting errors like this remaining all are fine.

looking at your zoning, can you determine what HBA this FA is zoned to. Also based on zoning do you have other FAs zoned to the same HBA ?  Trying to determine if it's an HBA, SFP, patch-panel issue.

On your problem host, check system logs prior to the event, particularly anything that the HBA driver has posted.

On your switch(s), identify the ports that the host uses and check the error counters. Make a note of what they are and recheck at regular intervals. Are you seeing any increase in error count that might indicate a HBA,cable or GBIC issue?

Also on the switch logs, determine if your HBA logged out or not around the time of the message.

And also we are getting  these alert from one of the server which is connected to same FA port

scsi: [ID 107833 kern.notice]         Requested Block: 13138554                  Error Block: 13138554

scsi: [ID 107833 kern.notice]         Vendor: EMC                                Serial Number: 02583008Q

scsi: [ID 107833 kern.notice]         Sense Key: Aborted Command

scsi: [ID 107833 kern.notice]         ASC: 0x44 (internal target failure), ASCQ: 0x0, FRU: 0x0

These are the h/w errors from the same server, which is getting internal target failure....

errors on the FC switch this FA is connected to ?

check the switch logs for the port behavior. It might be bad HBA even!

after changing SFP also we are getting same errors

SFP on the switch for HBA ? SFP on the switch for FA, SFP on the FA itself ?

SFP on the Switch

for the same server we are doing partition is there any impact or not?

LPARs ?  Have you had support look at the SFP on the FA ..any errors there ?

Hi dynamox,

We asked EMC Team about the issue they are saying that, they found Low light level on dir 10a port:0

low light means?

Also found low light level on dir 10a port:0

low light means your switch port is not providing strong enough "signal".  I don't know what switch you use but many provide low and high values for send and recieve when you look at the transceiver (SFP) properties.  If your switch is supported by EMC gather the logs and have them validate if that SFP is experiencing any issues. If it's not EMC then open a ticket with the switch vendor.
