Unable to access previously accessed device at nport ID 0xe8.

[Md.Shahabuddin]

Hi,

This is the error what i am geeting continously in dmesg

1/12/0/0: Unable to access previously accessed device at nport ID 0xe8.
0/4/0/0: Unable to access previously accessed device at nport ID 0xe8.

what can be done?

Bonjour,

I guess that you are in a SAN environnement. So "ioscan -fkn -C fc" should show hardware path 1/12/0/0 and 0/4/0/0. Right ? Post result please

Then begin to check SAN connectivity. I guess that 0/4/0/0 has driver /dev/fcd0 and 1/12/0/0 has driver /dev/fcd1. So to check, issue these 2 commands : "fcmsutil /dev/fcd0" and "/dev/fcd1" and post result

oups td0 and td1. Old system ?

Anyway. First thing : FC cards are connected.

But not in a fabric. It is a private loop. What kind of devices are connected in this loop ? Something like old FC10 JBOD ? Do you have san switches ? I suppose that no, but some ports could be configured in quickloop mode.

Post know "ioscan -fn -H 0/4/0/0" (no -k so that you rescan hardware) and "fcmsutil /dev/td0 get remote all"

Hi Eric,

We dont have any san switches here. Please find the above output.

[Torsten.]

Did you replace this disk by chance?

target 4 0/4/0/0.8.0.255.0.1 tgt NO_HW DEVICE
disk 1 0/4/0/0.8.0.255.0.1.0 sdisk NO_HW DEVICE SEAGATE ST318304FC
/dev/dsk/c3t1d0 /dev/rdsk/c3t1d0


Read the syslog - follow the advise about use of fcmsutil ... replace_dsk ...

[Md.Shahabuddin]

Hi,

Disk is replace long back and this error is coming from today. fcmsutil replace_disk i have tried but in vain.

[Eric SAUBIGNAC]

Back from lunch ...

target 4 0/4/0/0.8.0.255.0.1 tgt NO_HW DEVICE
disk 1 0/4/0/0.8.0.255.0.1.0 sdisk NO_HW DEVICE SEAGATE ST318304FC

and

Target N_Port_id is = 0x0000e8
Target Loop_id is = 1
Target state = DVS_OPEN_PLOGI_SENT

Same thing ... one disk is KO.

What model of disk array do you have ?

Eric

[Eric SAUBIGNAC]

n_PortID = 0x0000e8 --> Loop ID = 0x01

In an FC10 context, it means that disk in slot number 1 (slot numbering starts from 0 to 9) in Enclosure ID 0 is KO.

You should replace this disk
