creating non-existant lun 0 on fc60 using sc10 contoller

b polasky — Tue, 05 Aug 2003 20:02:08 GMT

We are setting up a disaster recovery site using the (2) disk cabinets each containg 4 enclosures of fc60 disks. We purchased the fc-60 disks cabinets from a hp var. my problem is - one of the disk fc60 disk cabinets does not contain any luns. It has no lun 0 or any other lun on it.

I know you need to use the amcfg command to bind/configure the luns but this one array has no luns period.
Does anyone have a trick to create the lun 0 so I can then start binding other luns on the disk enclosures on that particular disk cabinet? Help!

Which operating system? For windows use SM60, for hpux use AM60.
Which firmware FC60 has?

The os level is HP-UX 11.0.

The armserver software is using /opt/hparray/bin/AM60Srvr

The firmware version is not known at this time for the disaster hardware set up located at another site. But I do know that it will be later than what is on my source system - listed here.
SCSI Channel:ID = 2:1
Enclosure = 1
Slot (0-based) = 2
Disk State = OPTIMAL
Disk Group and Type = 0944B200113B44BFF1 LUN
Capacity = 17.0 GB
Manufacturer and Model = SEAGATE ST318404LC
Serial Number = 3BT23XZM
Firmware Revision = HP04 <======

Attach (not post) 'amdsp -a' output for this disk array

Looks like you assembled this FC60 by parts :)
There's no LUN 0 and LUN 31, and I think you need to call HP support for help. They will upgrade firmware and reload NVSRAM settings

I assume the LUN information showing up in your 'armdsp -a' is read from the discs. Therefore you should be able to overwrite any LUN information using 'amcfg -f'. This forces the LUN creation.
