Problem whit disk /HBA

[Zinky]

Isn't the EMC Symmetrix 5000 Series a VERY OLD array? And from the looks of the support matrix here http://www.hp.com/products1/serverconnectivity/mass_storage_devices.html#EMCiSCSI - it does not seem 11.31 supports it.


That is whty your info on the disk in scsimgr does not show multipaths sir...

Now I don't know if you can still safely use the legacy devices and just use PVLINKs. It may work -- but likely unsupported.

Here is EXAMPLE of a correctly multipathed disk (In this case an HP XP24K LUN presenetd on 4 CHAs/FC-Paths:

ioscan -m dsf:

/dev/rdisk/disk28 /dev/rdsk/c78t0d0
/dev/rdsk/c82t0d0
/dev/rdsk/c84t0d0
/dev/rdsk/c80t0d0

You should only use the native multipathing, no powerpath. IMHO this is the reason for trouble here.

Hi torsten, exactly

i need used ative multipathing, but I think so no compatiblity the EMC Symetrix whit Opeartion System.

I dont can install powerpath. HP-UX 11.31 and version power path have problem, the server crash constantly.

Whit HP-UX 11.31 dont no show these parameters??

[Zinky]

See my last 2 posts.

Your EMC does not appear to be recognised, multipathed by 11.31's mass storage stack. Yor disk info shows it clearly... if it did - it should show 4 paths. And it is not

Bottom line.. you likely HAVE an old Symmetrix 5000 series that IS not supported by 11.31's multipathing routines....

[Eli Daniel]

Thanks Alzhy, the information exist in link??

where can find information?? (www.docs.hp.com)

Ask your EMC person. Is the array an old 5000 Series!

If it is -- then it is likely UNSUPPORTED in 11.31


You can still however try using it - via PVLINKS but DO test if PVLINKS work.
