disks from hsg80 not appearing

[penelope_1]

Hello,

I am working with an EMA8000/HSG80 controller/Tru64 5.1B OS with ES40 Server. My array had been successfully built with raidsets and all were recognized by the OS.

Then I swapped 3 - 36G drives for 72G drives and rebuilt the 3 arrays associated with those drives. Everything appears correctly when I run my show commands (show raidset/show storage), but on the OS side it is not recognizing the new disks (raidsets). I ran hwmgr -scan scsi and when I run hwmgr -view devices I still don't see the new identifiers. The system has been rebooted several times. Not sure what else to try - any ideas as to why the OS can't see the new raidsets??

Thanks in advance for any info.

Hi,

Can you see the new raidsets if when you run "show units" from the HSG80...?

If yes, did you enable access to the units ?

Hope this helps,

Regards,

Rob

I can see them when I run show units and everything is Normal. Also, the access is All, same as the other raidsets. Any other ideas?

[Ivan Ferreira]

Can you post the commands that you have run in the HSG controller?

Can you post the show unit command?

Have you enabled host access?

I have attached a document with the show units full/show storage full and hwmgr -view devices from the OS. Any ideas are greatly appreciated!
At this point my only thought of next step is to delete the 3 raidsets and re-add them, but it doesn't look like there is anything wrong with them so I don't know if that would even make a difference.

Hmmm... Everything would appear to be set up correctly.

The rebuilt arrays might have been known to the OS with a different LUN ID, but as they have the same Identifier things are getting confused.

Do you see any stale devices if you look at "hwmgr show scsi -full" ?

If yes, then try deleting them with hwmgr and dsfmgr, and rescan the SCSI bus.

Hope this helps,

Regards,

Rob

As Rob said, output of "hwmgr show scsi -full" will give more information.
Please post it.

Thanks - I'm making progress! There were stale HWID's which I removed with hwmgr. I didn't know the previous/current dsk's, so I didn't use the dsfmgr command. When I run hwmgr view hierarchy I can see the raidsets, but they don't show up in hwmgr -view devices or diskconfig. Do you know how I can get the dsk# now for each of the 3 identifiers so that I can use them?

69: disk IDENTIFIER=2 dsk9
112: disk IDENTIFIER=5 SCSI-WWID:01000010:6000-1fe1-0010-5f90-0009-1130-5225-0063
110: disk IDENTIFIER=3 SCSI-WWID:01000010:6000-1fe1-0010-5f90-0009-1130-5225-0069
73: disk IDENTIFIER=6 dsk13
74: disk IDENTIFIER=7 dsk14
75: disk IDENTIFIER=8 dsk15
76: disk IDENTIFIER=9 dsk16
81: disk IDENTIFIER=11 dsk21
80: disk IDENTIFIER=12 dsk20
113: disk IDENTIFIER=4 dsk28
111: disk IDENTIFIER=10 SCSI-WWID:01000010:6000-1fe1-0010-5f90-0009-1130-5225-0071

Hi,

Use dsfmgr to delete the devices by the hardware identifier...

So as an example for your IDENTIFIER=5 disk...

hwmgr delete component -id 112
dsfmgr -R hwid 112

...repeat for the others then...

hwmgr scan scsi

And hopefully everything will be back on a dsk device.

Cheers,

Rob
