Sun Storage T3 Array
Sun Storage 6020 Array - Version: Not Applicable and later [Release: N/A and later]
All Platforms

Goal

Description

In order to provide you the most accurate fix, please validate each statement under "Symptoms" is true for your environment.

These symptoms will link you into relevant content that will:

1) tell you how to validate the listed symptom and
2) tell you how to fix the symptom if it is true for your environment.

The listed symptoms are ordered in the most appropriate sequence to isolate the issue and be certain about the related fix. Please do not skip a step.

Symptoms:

- Device disappeared

- Device offline

- Cannot see device in luxadm commands

- Can not see device in format

- Device is unconfigured

NOTE: This document assumes that Oracle/Sun Branded HBAs are installed.
See DocID 1282491.1 How to identify Oracle Fibre Channel (FC) HBA and CNA Cards and Their Slot Locations

Solution

Steps to Follow

NOTE: This document is a sub-set of Troubleshooting Fibre Channel Devices from the OS (DocID 1009557.1)

The steps below will help confirm that the HBA is visible to the OS and the devices can be seen from the HBA.

1.Use the "luxadm -e port" command to verify HBA has established communication with a node.

Example:

# luxadm -e port
/devices/pci@1f,4000/SUNW,qlc@4/fp@0,0:devctl   CONNECTED
/devices/pci@1f,4000/SUNW,qlc@4,1/fp@0,0:devctl CONNECTED

NOTE: "CONNECTED" means the HBA has established a communications with some other node (Initiator or Target).

"NOT CONNECTED" means the HBA has not established a communication with some other node or connecting to a switch that has no target (including not zoned to a target).

If 'luxadm -e port' shows NOT CONNECTED for the device path identified, choose the appropriate document to continue troubleshooting:

Troubleshooting Sun StorEdge[TM] 33x0/351x Configurations (Doc ID 1005313.1)
Troubleshooting Sun StorEdge[TM] T3 configuration (Doc ID 1012673.1)
Troubleshooting Sun Storage[TM] 2500 and 6000 RAID Array Disk Failures (Doc ID 1021055.1)

2. If 'luxadm -e port' shows "CONNECTED" then use the device path output and verify that the devices can be seen in "luxadm -e dump_map ."

Examples:

T3:

# luxadm -e dump_map - /devices/pci@1f,4000/SUNW,qlc@4/fp@0,0:devctl

Pos Port_ID Hard_Addr Port WWN         Node WWN          Type
0    620000    0   210000e08b05b4c1 200000e08b05b4c1 0x1f (Unknown Type)
1    620100    0  50020f230000a81b 50020f200000a81b 0x0  (Disk device)
2    620300    0   210000e08b052b82 200000e08b052b82 0x1f (Unknown Type, Host Bus Adapter)

3510:

# luxadm -e dump_map /devices/pci@1f,4000/SUNW,qlc@4,1/fp@0,0:devctl

Pos AL_PA ID Hard_Addr Port WWN         Node WWN         Type
0     1   7d    0      210100e08b27eaa6 200100e08b27eaa6 0x1f (Unknown Type,Host Bus Adapter)
1     9f  2c    9f     256000c0ffc00f26 206000c0ff000f26 0x0  (Disk device)


Record "Port WWN" of the array in question.

"50020f2",indicates  T3
256000c , indicates 3510
This WWN will be referenced in multiple steps.

NOTE: If Port_ID ends in "00" or  "13", this indicates switch attached
storage.

3. If the array is switch attached then verify that device is configured in the "cfgadm -lao show_FCP_dev" command.

Example:

# cfgadm -lao show_FCP_dev


c5                        fc-fabric connected    unconfigured   unknown
c5::50020f200000a81b,0    disk      connected    unconfigured   unknown
c5::50020f200000a81b,1    disk      connected    unconfigured   unknown
c5::50020f200000a81c,0    disk      connected    configured     unknown
c5::50020f200000a81c,1    disk      connected    configured     unknown

Note: Receptacle should be "connected". Occupant should be "configured".

4. If Occupant is "unconfigured", then follow the steps below:

"cfgadm -c configure "     <--Configure the device
"cfgadm -lao show_FCP_dev "<--verify the Occupant changed to configured
"devfsadm"                 <--- rebuilds the device tree

Example:

T3:     # cfgadm -c configure c5::50020f200000a81b
3510:   # cfgadm -c configure c7::256000c0ffc00f26
# cfgadm -lao show_FCP_dev
# devfsadm

5 . The steps above confirm that the HBA is visible to the OS and the devices can be seen from the HBA. If there is still a problem, return to:
