https://community.hpe.com/t5/operating-system-linux/lp9802-with-rhel3-update4/m-p/3556959#M17971 I have installed the LP9802 with RHEL3 update4 based on the document in emulex website. The SAN storage array present 3 luns to the box, and I see the 3 luns. But I always see error in my /var/log/message with "kernel: SCSI disk error: host 0 channel 0 id 2 lun 0 return code=4000) It didn't impact all the luns that I am seeing but it is arroying. In my /proc/scsi/scsi it shows <BR />Attached devices: <BR />Host: scsi0 Channel: 00 Id: 00 Lun: 00<BR /> Vendor: DGC Model: RAID 5 Rev: 0207<BR /> Type: Direct-Access ANSI SCSI revision: 04<BR />Host: scsi0 Channel: 00 Id: 00 Lun: 01<BR /> Vendor: DGC Model: RAID 5 Rev: 0207<BR /> Type: Direct-Access ANSI SCSI revision: 04<BR />Host: scsi0 Channel: 00 Id: 00 Lun: 02<BR /> Vendor: DGC Model: RAID 5 Rev: 0207<BR /> Type: Direct-Access ANSI SCSI revision: 04<BR />Host: scsi0 Channel: 00 Id: 01 Lun: 00<BR /> Vendor: DGC Model: Rev: 0207<BR /> Type: Direct-Access ANSI SCSI revision: 04<BR />Host: scsi0 Channel: 00 Id: 01 Lun: 01<BR /> Vendor: DGC Model: RAID 5 Rev: 0207<BR /> Type: Direct-Access ANSI SCSI revision: 04<BR />Host: scsi0 Channel: 00 Id: 01 Lun: 02<BR /> Vendor: DGC Model: RAID 5 Rev: 0207<BR /> Type: Direct-Access ANSI SCSI revision: 04<BR />Host: scsi0 Channel: 00 Id: 02 Lun: 00<BR /> Vendor: DGC Model: Rev: 0207<BR /> Type: Direct-Access ANSI SCSI revision: 04<BR />the first 6 is correct because I have 3 luns with SPA and SPB. But I don't know why it also has the last one. Any help will be appreciated.

I also hoped one of the many people smarter than me would be of assistance. To no avail.<BR /><BR />So don't look for a lot of helpful info from me.<BR /><BR />It appears to me that one of your LUN's may not be set up correctly with its World Wide Name(WWN). <BR /><BR />In genreal this is done by the SAN administrator. Perhaps that will get things started on this issue.<BR /><BR />SEP Fri, 03 Jun 2005 19:03:32 GMT https://community.hpe.com/t5/operating-system-linux/lp9802-with-rhel3-update4/m-p/3556960#M17972 Steven E.
