Simplivity TIA card replacement w/o redeploy?

[zebansho]

Hi; we've got an 3 node Simplivity environment. We got third party parts support to get a new TIA board to replace a faulty one, but the new card is giving me UUID mismatch errors. I've previously had HPE support fix this for us, but they will no longer sell us support on this model.

Is there any way I can get this board to come up? What if I take the nvram module from the old one? (I don't think that part is faulty).

If no one knows how to do this, how bad is redeploy? Can I do it w/o bringing down the VMs on the other 2 nodes?

Thanks so much if anyone can answer any part of this.

Hi @zebansho ,

This may be caused by the UUID generated on the host side via the UUID calculation of the new tia. You may need to reconfigure your host's UUID via vCenter by performing the following steps.

1. Login into the OVC in question.

2. Run the following command to obtain the GUID to be later used in vCenter's MOB:

echo "NEW_MOB_GUID: `sed 's/-//g' /var/svtfs/0/myguid`"

3. Run the following 2 commands to obtain the VM MOB ID to be used to find the OVC within the vCenter MOB:

OVCGUID="`cat /var/svtfs/0/myguid`";echo "OVCGUID: ${OVCGUID}"

echo "OVCVMID: `psql -x -c "select hms_platform_id from node where id='${OVCGUID}';" |awk -F: '/hms_platform_id/{print $NF}'`"

4. Power down the OVC

5. Navigate to VM in MOB reconfigure task using VM ID from step 3 output...

https://<vCenter_IP>/mob/?moid=<vm_id>&method=reconfigure

6. Delete the entire contents of the value field and copy the following text
using the lowercase GUID from step 2's output...

  <spec>
        <uuid>NEW_MOB_GUID</uuid>
        </spec>

7. Invoke the reconfigure method and start the OVC one again and see if the svtfs service starts.
