Solaris does not see Quantum superloader

NicovanVlietAug 14 2013 — edited Aug 27 2013

Hi,

I have a new Quantum Superloader3 with an LTO5 drive. This machine has a SAS connection tothe Solaris 10 server (x86). It is anX4270

In the server I installed a Sun/Oracle SAS card with a raid controller on it. It is actually an Adaptec.

When I boot the server i can press Ctrl-A and get into the adaptec bios. This sees 2 controllers. The build-in (for internal disks) and the external I installed.

In the external controller it also sees the superloader. There are ofcourse the options to configure RAID, but I have only the loader attached.

After Solaris is booted it does not see the Quantum. I tried lots of commands like devfsadm drvconfig, tapes and probably some more that I have forgotten.

So there is no 'st' device in the devices tree and no under /dev/rmt/1. /dev/rmt/0 is already in use by another tapedrive. Also nothing in /dev/changer/scsi (except the other one)

There is another SAS controller installed. This is an LSI without RAID. If I attach the superloader to the LSI everyting works fine. Device nodes get made and the backup software sees the loader and the drive in it.

Apperently I can not use the Quantum with a SAS controller that has RAID on it.

Is this correct?

Or do I have to do some additional config I do not know about?

Can anyone tell me?

Hello,

If you can see the SAS card on BIOS, there should not be any problem with the SAS card hardware itself. Most probably your Solaris 10 requires the appropriate patch for this card to work. Refer to Sun System Handbook for the required patches for your PN or to Quantum Superloader documentation.

Rei

Thanks Reidod,

I did a 'smpatch update'.

And the cable works on the other controller, so that looks good to.

But no change. It is still not recognized. Where is that handbook these day's? Oracles site (My Oracle Support) is so unclear.

The System Handbook is available at the following link:

https://support.oracle.com/handbook_private/index.html

You will need MOS credentials and be logged in, to be able to get to it.

Be aware, it has information ONLY for those components with a Sun/Oracle part number and does not describe anything third-party.

Your troublesome controller needs to be configured in the OS before you're ever going to be able to get to any peripheral connected to that controller.

Thank you rukbat,

The adapter was sold to me as a sun hba. Partnumber 'SUN375-3537 8-Port SAS RAID External HBA'. I wanted an official sun hba.

The adaptec bios sees this and the internal one as STK, wich I think means storagetek and offical.

the server itself is basically under contract, although I let it slip a few days and I expect the contract to be active again within a week.

So I could raise a support case.

How do I configure the hba in the OS?

Working in a research group at our university I am not an real expert on this, and the last install of a SAS hba I did on the server is about 3 years ago.

regards,

Nico

Nico,

Go to the Handbook and select the "Components" link at the top of the site.

Navigate to the section for "SCSI" and then navigate further to the "PCI Express SCSI Host Adapters" portion of that next page.   See the entry for your "8-Port 3Gbps SAS RAID HBA (External)"

When you view that resource page, you will find product footnotes and a couple of links for the P/N 375-3537 card:

  1. RAID Management Software Documentation
  2. Sun StorageTek 3 Gb SAS RAID HBA, External Documentation

Give them a shot.

Edit:   I haven't reviewed those links.  I simply copied them to my reply.

Hello Nico,

This SAS HBA RAID card is used to connect the host to a JBOD (ie Sun J4200, J4400, J4500). I am not sure if it will work if you connect a tape device to it like your Quantum Autoloader as, according to quantum superloader support page below, it says that this Autoloader is not recommended to be used with a RAID Controller.

Affordable Tape Library - SuperLoader 3 - Support and Services

I would use this PN: 375-3641 on the host. It is a SAS2 PCI-e card to connect to a Tape Library. Best way is to log a call to Oracle, if you can.

Regards,

Rei

Hello Rei,

I was actually thinking allong the same lines. I am logging a call with Oracle to see what tey say. Thanks for providing the Part Number.

I will post Oracle's final reply here.

Answer

Hi,

Sorry I am a bit late with this.

I got the answer from the Oracle support. Bottom line:

SUN RAID CONTROLLERS DO NOT SUPPORT SAS TAPEDRIVES

Check document ID 1020986.1.

https://support.oracle.com/epmos/faces/DocumentDisplay?_afrLoop=1397015074115115&id=1020986.1&_afrWindowMode=0&_adf.ctrl-state=14ohu6985_21


Some quotes from this one:



SAS tape drives are supported on the:
SAS-1 Pandora (PCI-Express) HBA (SG-XPCIE8SAS-E-Z)
SAS-1 Mimas (PCI-Express Module) HBA (SG-XPCIE8SAS-EB-Z)
SAS-2 Erie (PCI-Express) HBA (SGX-SAS6-EXT-Z)
SAS-2 Erie (PCI-Express Module) HBA (SGX-SAS6-EM-Z).

NOTE: Minimum Solaris required is Solaris 10 Update 10 (08/11).

SAS tape drives are not supported on SAS-Raid HBAs.
============================================
The following provides SAS HBA support information:
No SAS tape drives are supported on SAS-Raid HBAs. They need the Pandora SAS HBA.

Currently SAS is only supported on the HBA Pandora(codename) HBA p/n 375-3487.
