DS2405 working on a HP K5xx

[Felipe Martinez]

Hello:

Does anyone has a ds2405 working on a HP K5xxx? please help me, i allready install it but i can´t create logical volume

[melvyn burnard]

So what OS version, and what type of card do you have this connected to?
I have my doubts this disc subsystem will work on hte K boxes, as they are LVD, and there is no LVD interface for the K-class.

[Felipe Martinez]

The ds2405 is FC and the card used in my host is A6685A.

Melvin:

Is the same situation, i want to install it but the HP engineer tell me than de A6685A is not supported on the core i/o.

[Felipe Martinez]

the os is HP-UX 11.0

Ok, need to start at the begining I suppose.

1) Can you see the disks with an IOSCAN?
2) Can you PVCREATE the disks?
3) Can you add them to a volume group?

4) If all the above are true what error messages are you getting when creating the logical volume?

Ah yes, I see the ds2405 is an FC jbod. Too many disc products, too fast.
Mark's questions need to be answered.
Also, I believe you may need to ensure there are no patches missing from hte system, to allow this to work.

The other thing to keep in mind is that the DS2405 does not autonegotiate speed on the Fibre Channel.

If I remember correctly, the FC HBA you are using is a 1gb interface, you will need to flip a dipswitch on each interface card of the DS2405 for it to work at 1gb speeds.

You will have to pull the card from the DS2405 chassis to make the change.

[Felipe Martinez]

I enable the speed to 1GB on both controlers. I can see the disc with ioscan and diskinfo, lvm is only the problem.

[Mark Smithers]

I have just run into what I think is the same issue.

To test my theory, do a diskinfo on all the devices e.g. diskinfo /dev/rdsk/c4t0d0 and see if the number of bytes per sector comes back as 520. If so, then these disks come from a VA and need to be reformated. This can be done by installing Commandview and use the JBODfmt command to zap the disks back to 512 bytes per sector.

Mark:

You are right, one week before, i found a note, i installed commandview, reformat the hard disks and everything worked fine.

Thanks for your repply.
