  • 1.  how-to Restart HMC when hmcshutdown fails??

    Posted Tue November 22, 2022 02:12 PM
    Running  7063-CR1  
    MH01934 - HMC V9R2 M953

    web interface get's 500 response
    CLI gets the following to any command:

    > lshmc -v
    connect: Connection refused
    A connection to the Command Server failed.
    >

    > hmcshutdown -r --force
    connect: Connection refused
    A connection to the Command Server failed.
    >

    Can the HMC be restarted from the CLI when the HMC is in this condition?   
    If not, I'd like to recommend IBM create a method to run the OS shutdown/reboot command to restart the HMC.

    Hi,

    If you have the HMC service processor online via the network then you may be able to restart from there but it appears your HMC is truly stuck.
    I can't say I have seen that before in a decade of using my HMCs.

    You may have to physically press the button on the HMC or yank the power cords. 

    IBM can investigate and find out if this is a regular issue by searching the Support Case records and start working a solution.

    For your request for a new feature or any other ideas, there is an IBM Request For Enhancement (RFE) process.

    I recommend working with your local IBM representative or IBM Business Partner.

    Then start here https://www.ibm.com/support/pages/how-submit-request-enhancement
    Just to add confusion this was called the RFE process but renamed "Ideas" or some call it Aha.  IBM does stand for It's Been Moved!

    Cheers, N

    Hi Tom,

    if you have configured the bmc port tcpip settings you can connect to the bmc UI or with ipmitool to your CR1.
    UI ist self-explanatory. with ipmitool you can use:
     
    Server power status: ipmitool -I lanplus -H <Address-BMC> -U <username> power status (asks for password) 
    >> Chassis Power is on
    Server power reset: ipmitool -I lanplus -H <Address-BMC> -U <username> power reset (asks for password)
    >> Chassis Power is off
    Server power reset: ipmitool -I lanplus -H <Address-BMC> -U <username> power on (asks for password)
    >> Chassis Power Control: Up/On

    CHers Patrick

    Patrick,
    I'm not that familiar with the BMC stuff... but isn't that a port on pSeries frame, and not the HMC itself?
    My issue is the HMC isn't useable, and it's in a lights out setup several hundred miles away.  I'm wondering if there's a method I'm not aware of to restart it, without someone having to physically being there

    The HMCs called CR1 and CR2 are Power-based computers themselves.
    They have BMC services processors built in.

    If you have previously put the CR1 BMC on the network then you can "talk" to the BMC to reboot the CR1.

    If the BMC is not on the network: phone a friend or enjoy your trip.

    And while you are at the HMC put the BMC on the network for next time.

    I hope you can get your HMC back online.

    Hello Tom,

    since CR9 (CR1 and now CR2) I have always configured the remote management to be able to fix exactly such situations. SSH sessions were almost still available and a restart was possible.
    Also Remote Upgrades was little bit more unstressed.

    Maybe configure at the next opportunity

    Best regards

    Manfred

    I’m not sure what you’re suggesting I configure..
    If you’re talking about ssh level access (CLI), then please look closer at my original message. That’s exactly what I’m trying to do, and the hmcshutdown command fails at the command line.

    If there’s something else you’re suggesting I should have configured, please elaborate..

    Thanks
    Tom

    Hello Tom,

    with this Interfaces (IMM2 = CR9, BMC = CR1 and openBMC = CR2) you communicated with one underlaying hardware interface. These are usually accessible even if the HMC interfaces / services ("hmcshutdown") no longer respond.

    Please see here:
    https://www.ibm.com/docs/en/power9?topic=rack-cabling-mounted-7063-cr2-hmc
    Also this:

    Best regards
