SAM not showing EMC Disks

[Paul Bardeskar]

Hi All,

I am facing a problem in RP 5470 system.

We have recently Added 8 Clarrion disks having dual path at EMC Side. It is shoing properly 8x2 = 16 Deivces after ioscan has performed.

But in SAM it is showing only 1 Device and 16 Paths. In sam it should show 8 devices and not 1 device

Below is the screen shot of ioscan==>

We are having dual path, which are:
0/5/2/0.2.15.x.x.x.x and
0/5/2/0.2.47.x.x.x.x

ioscan is showing the proper results, but SAM is not showing the results.

Screenshot of SAM ==>
0/5/2/0.2.15.0.0.0.0 16 Unused -- 53248 DGC CX

Please provide assistance, Appreciate your time in reading this and helping me out.

Shalom Paul,

1) insf -C disk (check sam again)
2) If practical boot your system and see if it helps. Item 1 happens during a boot.
3) If 1-2 do not help, make sure on the disk array, the World Wide Name of the fiber card is on the LUN.

Hi paul,

It is problem you see several times with diskarray's. The only was to solve this is working with the command line instead sam.

[Paul Bardeskar]

I appreciate your inputs SEP, I have done the system reboot(insf -C disk). But that has also not worked.

I will check on the disk array, for the WWN of the fiber card is on the LUN.

Thanks Luk but i can get the proper results on sam on other HP-UX system.

Hi Paul,

I can only advise you to compare the patch and firmware revisions between the working and non working environment.

[Christine Hartman]

Hi there,

I think you may need some patches...check for this one: PHCO_32397....there were some known problems with SAM detecting all SAN attached disks.

Good luck!
