HP DL585 and MSA1000 Problems
On the DL385 I will do an "lsscsi" and see the SAN and devices (/dev/sda) I created on the SAN. On the DL585 I can't see anything but the dvdrom when doing an "lsscsi". I have tried swapping HBA's to see if that helps, but it didn't. When I stick the HBA from the DL585 to the DL385, it works fine there too (which it should because they are the same type of card).
They are both loading the ql2xxx driver. I am not sure where to go from here and didn't know if you had any pointers.
I guess I should also ask the question one last question. Do I have to do any special configuration from the SAN to allow additional machines to connect or should the SAN automatically take care of this?
Please let me know if I can provide more information to make this question easier.
Thanks,

Re: HP DL585 and MSA1000 Problems
1) If you install PSP for SLES, new drivers will be installed and you may see the SAN.
2) Could be a bad switch, contact HP hardware support for some help.

Re: HP DL585 and MSA1000 Problems
The only question I have is both the DL385 and DL585 have the same version of SLES 11 and the same HBA. The DL385 can connect to the SAN, while the DL585 cannot. (as a matter of fact, I have tried multiple DL585's).
If I use the ports with the DL385, it can see the SAN, so it doesn't seem to be a problem with the switch. I don't have to assign LUN's to Servers or anything like that do I? Will the MSA1000 just allow any server to connect (if I have the right driver and hba)?
Thanks,

Re: HP DL585 and MSA1000 Problems
I have also tried multiple ports in the switch with the server (DL 385) that can access this SAN, so it doesn't seem to be a switch problem.
On the SAN I have SSP (Selective Storage Presentation) disabled. By disabling this option, doesn't this mean that any server can access the SAN and any LUN? At this point I could only think of it being a SAN misconfiguration or a driver problem.
Any help to proceed further would be appreciated.
Thanks,

Re: HP DL585 and MSA1000 Problems
If you don't have SSP enabled and there are other systems on the SAN that could see that disk, then possibly one of them has grabbed the disk and popped a SCSI Reservation on it which will effectively lock everyone else out.
Sounds to me like this is the mostly likely cause of your problem. Clearing the SCSI reservation maybe problematic. I would enable SSP, then delete that disk from the MSA, re-create it, present it to the host HBA(s) you want and then see if you can see it afterwards.

Re: HP DL585 and MSA1000 Problems
PSP is commonly updated 3 months or so after a major SLES release.
If SLES 11 is over 3 months since release you should be able to find a PSP version that supports it.
