Question on PowerPath & Solaris
Hi all,
I am running PowerPath 5.0 on a Solaris 10 host and someone (maybe by mistake) set the class 'symm' to unmanged...
At the time being the host sees 124 devices and when I issue 'powermt display dev=all' I do see all those devices (and all paths are alive). But when I run 'powermt display ports' there is nothing shown.
'powermt display options' shows the following:
Default storage system class: all
Show CLARiiON LUN names: true
Path Latency Monitor: Off
Path Latency Threshold: 0 Sec.
Storage
System Class Attributes
------------ ----------
Symmetrix periodic autorestore = on
status = unmanage_incomplete
CLARiiON periodic autorestore = on
status = managed
Hitachi periodic autorestore = on
status = managed
Invista periodic autorestore = on
status = managed
HP xp periodic autorestore = on
status = managed
Ess periodic autorestore = on
status = managed
HP HSx periodic autorestore = on
status = managed
I saw that there's no entry for 'class=symm' in the /kernel/drv/emcp.conf'-file and when I run 'powermt manage class=symm' I get this following message "Error: cannot manage. verify state of the class Symm."
Has anybody an idea how I might recover from this situation (without rebooting the system)?
Thanks inadvance,
Stefan

2. Is/Has MPxIO been installed on the host?

the policy is set to "SymOpt"... I'm not sure if MPxIO is enabled - do you how I can find out?
Thanks,
Stefan

yes... it's a Solaris 10 host and MPxIO is set to "mpxio-disable="yes";" in /kernel/drv/fp.conf...

In /kernel/DRV/fp.conf file what is mpxio-disable set to?
(I'm assuming this is Solaris 10?)

thanks four your quick answer.
I will collect the grabs and open a service request... I'm really curios if there's a way to recover without rebooting the system!?

I've seen this "unmanage incomplete" message once before but it was a Clariion environment. In your case, I don't think the "unmanage" option was set mistakenly by someone; it's more likely something (possibly MPxIO) interferring with PowerPath. EMC primus solution emc205612 along with emc134813 and emc201300 cover a similar topic but I would suggest you should open a Service Request with EMC for analysis of the emcgrab.
