    Morning,

    Our wintel team are building a new Opscenter instance from the current 11-03 OVA . They've followed the sizing 12 cores and 36  .They've done the initial deployment OK but after reboot the server just hangs . Anybody seen this before , have any idea where to start?

    Hello Gary

    Do you have some more details, maybe a screenshot or where it 'hangs'? One gotcha is that you often need the DNS names configured. If you opsvm server cant look it up, it often wont start the web interface because it cant resolve where it needs to run. 

    Maybe compare your install experience with this guide here:

    Hi William, it's a dark site so can't add any screenshots . Basically our wintel team have built the Opscenter server from the combined OVA, and I can SSH onto it ok . The initial loading screen comes up https://opcenterserver:443/portal. This is very sluggish loading, with timedelay between hitting keystokes on the login screen and the screen showing them. The VM has been given plenty of cores and memory though.  I put in the sysadmin default credentials , screen goes clear , i assume to try a login , but thats it , nothing comes back . Though oddly if I log in on the 20961 port it responds ok
    The management server i'm connecting on and the opscenter server are both on the same storage management vlan with no firewalls between

    one thing the wintel team havent done is the SSL communication part , still using the selfsigned defaults  - would this cause the issue? Does anyone have  a straightforward document on how to do it ,  we've got the combimed management server build and teh probe server , boyth built from the OVAs , but the hitachi qucik start and Opscenter manuals are up to the usual confusing standard :-)

    No, it should work with the self-generated certs just fine.

    Hello Gary

    Seems really odd. Might need support to take a look.

    Maybe try disabling selinux. You can do this by logging into the appliance and doing a 

    setenforce 0 
    /opt/hitachi/Base64/bin/hcmds64srv -statusall
    /opt/hitachi/Base64/bin/hcmds64srv -stop all
    /opt/hitachi/Base64/bin/hcmds64srv -statusall
    /opt/hitachi/Base64/bin/hcmds64srv -start all

    If you want to disable it with boot you can edit the /etc/selinux/config file and set it permissible.

    If you want to enable it again you just type:

    setenforce 1


    Maybe it's with the extra inspection and security. I'm shooting in the dark a little, but worth a try if you'd like.

    Hi William, I passed to support and they've come back asking us to implement the CA certificates. Now our wintel chap has looked at the quick start and installation guides and is stuggling with the usual wonderful Hitachi manuals :-) Do you know of any easy step by step guides for implementing them on an OVA build Opscenter and a probe center 

    Cheers

    Hi.  May be not at all related as Support had already asked to use CA Certs, and I don't know what OS is being used here. We use self-signed certs, and we also had similar hanging issue and even few components will not open from main portal page, and will show them as 'Unavailable', instead of 'Ready'.  Then Support suggested to upgrade OEL from 8.6 to 8.8/8.10. We did that and it repaired some bad RPM or Software version related to the older OEL 8.6. (Ofcourse, in case you are also using OEL). And, after that no issues at all.   Thanks

    Hello Gary

    I'm working on updating a guide on the very matter. Give me a week or two. Else I can maybe share a 'cheat sheet' if that helps.

    Regards

    William
