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

    1. What is the policy of the visible devices in 'powermt display dev=all'

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

    Hi,

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

    Thanks,

    Stefan

    Hi Rob,

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

    Hi Stefan,

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

    Regards,

    Hi Rob,

    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!?

    Hi Stefan,

    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.

    Regards,
    Rob
