I have Sparc server, V240, with 2 internal disks, HBA(QLA2342), connected to Storage type HDS AMS500.

There is any procedure how to megrate from internal scsi boot disk to a boot the solarin from LUN on the SAN? (with and without MPxIO)

thanks

Top of my head answer, no.

Think about the drivers that need to be loaded to get the cards to be able to contact the SAN.

So there is no option to do boot from LUN with STMS(multypath)?

 

If I have a server that running with MPxIO, the only way to do boot from SAN , is by using one lun that come via HBA that will be MPxIO-disable=yes.

 

?!?!?

Present the SAN LUNs, use live upgrade to move the image, reboot.

There are some issues around multipathing in here – mpxio doesn’t support the AMS last I checked – but thats the easiest way to do it.

What is your resources to say that AMS500 doesn’t support MPxIO?

I using MPxIO for data in V240 connactted to AMS500.

And now I try to do boot from SAN.

I haven’t seen code go into mpxio that supports HDS midrange failover. It could be that the AMS supports TPGS multipathng but … I haven’t heard either way.

If you had to fake out mpxio by saying the AMD was symmetric then you are probably not in the proper config but HDS is the one that says yes or no.

Why I cannot download the FCode into the HBA QLA2342????

I must download the FCODE qlc23xxFcode1.16 in order to see the Luns from the PROM.

NOTE : solaris10(11/06), server type V240.

Some outputs :

#>luxadm qlgc_s_download

Because you’re trying to use the Sun fcode download utility with native Qlogic HBAs. (Not Sun branded Qlogic HBAs….)

This is really a question for QLogic support and not Sun support, as luxadm again is meant to be used with legacy Sun 2Gb HBAs and is not meant for a non-Sun HBA.

 

So I would use their support forum to get some insight on this:

In short though, you probably need QLogic’s SANsurfer CLI utility to flash the FCode on the HBA.

the problem was fixed 🙂

 

I download the Fcode version 1.16(found on the Qlogic website) by using the SANSurferCLI.

scli -> Update Flash -> reboot(init 6)

 

Then I suceeded to see the luns on PROM, by using probe-scsi-all, show-devs, show-disks.

the device path changed after the Fcode downloaded

from -> /pci@1d,700000/fibre-channel@1/fp@0,0

to -> /pci@1d,700000/QLGC,qlc@1/fp@0,0

 

So I suceed to do also boot from SAN, by creating new lun on this solaris, and by using Live Upgrade to lucreate the current rootdisk(and the swap) to the LUN root disk.

 

Then luactivate <Lun_root_file_system_lu>

init 6

Then the system is UP without local disks !!!!

🙂

thanks
