Symptoms

A failed disk has been reported in a hardware raid volume, but there is no target number listed

- Solaris (raidctl)

raidctl -l <volume>

Example:

Volume			Size	Stripe	Status	 Cache	RAID
	Sub			Size			Level
		Disk					
----------------------------------------------------------------
c1t0d0			279.3G	N/A	DEGRADED OFF	RAID1
		0.1.0	279.3G		GOOD	
		N/A	279.3G		FAILED	<------ disk status: failed, disk target: not available


- <strong>OBP (fcode)</strong>

Select &lt;scsi controller&gt;

Example:

- ok select scsi:

{0} ok select /pci@0/pci@0/pci@2/scsi@0

- ok show-volumes
  Volume 1 Target 0 Type IM (Integrated Mirroring)
  Degraded Enabled     
  2 Members                585805824 Blocks, 299 GB
  Disk 2
  Primary Online
  Target 1 HITACHI H103030SCSUN300GA2A8
  Disk 3
  Secondary Missing Out Of Sync <------------ disk status: missing, out of sync
  Target ff                     <------------ disk target: ff, not available

Changes

Cause

- If the target number listed (n/a, ff), it might indicate the following
- failed disk (but even if the disk is replaced it may not resolve the problem)
- lsi controller is in a confused state
- lsi controller hardware raid volume configuration is in an inconsistent state
- Corrupted volume, not able to read the volume correctly

Solution

1. Verify that the system has the latest system firmware and the LSI controller (driver) patches. It will prevent future errors related to the same issue.
2. Open a Service Request with Oracle Support, proceed with the next step
3. If the disk has NOT yet been replaced, replace the disk marked as Failed/Missing/ N/A. If there are still failures, proceed with next step
4. Power-cycle the system by disconnecting/connecting all power-cables, so that the LSI controller will be resetted. If a powercycle can't be done, you can run reset-all from the OBP. if there are still failures, proceed with next step
5. Backup data on hardware raid volume, re-create the hardware raid volume and restore data on the hardware raid volume.
