HP9000 N4000 and MA8000 storage

[Dennis Rhodes]

In the above config, with only one FC HBA in the N4000(1/0/0/0.1.1 )and 3 luns presented from the MA, the following IOSCAN is produced.The paths 1/0/0/0.1.1.255.0.0.5 1/0/0/0.1.1.255.0.0.6 1/0/0/0.1.1.255.0.0.7 and 1/0/0/0.1.2.255.0.0.5 6 & 7 are correct.Could anyone please explain the other devices shown.

Dennis,
I suggest you do a 'SHOW CONNECTIONS' on the MA8000 and check the setting for 'Operating System'. I think the default is 'Windows' (what else?). Set it to 'HP_VSA' if possible, else 'HP'.

> set CON_NAME OPER=HP_VSA

[Dennis Rhodes]

Set to HP or HP_VSA makes no difference.

Did you reboot the servers and do a new IOSCAN after the connection characteristic was changed? It looks like you are running with SCSI-2 and the CCL disabled, correct?. Is this a single or dual-controller configuration? Are there units D0, D1, D2, D3 or D4? defined?

Can you try and set the UNIT_OFFSET of the connection to 5, so that the first unit is mapped to LUN 0?

[Dennis Rhodes]

no servers not rebooted.SCSI 3used and CCL not disabled.Units presented are D5 D6 D7 D105 D106 D107

Dennis,
there is a note in the 'Installation and Configuration Guide' that says: "LUNs created on the Array must be assigned consecutively starting with LUN 0".

What I don't understand is that the CCL is not visible. I have a little experience with EVA & HP-UX and I can see the CCL there.

We changed the mode to HP_VSA and rebooted and the phantom devices have gone.Thanks for your help.
