Development (xTF)

This page is for tracking any known problems with the RTS Virtual Infrastructure, or potential development/improvement ideas.

Known Problems

DRS Failed to relocate VM at power up

• 6 Aug 07 - UKTraderD3 had been shut down (no change made), on power up, the VM tries to relocate from UKLONESXP1 to UKLONESXP2. But fails with "Failed to relocate virtual machine 'UKTraderD3' in RTS". Reattempt to power on 10 mins later succeeds (including relocation).

High ESX disk write

• 4 Sep 07 - High disk write being seen on UKWOKESXGTT2, being generated by the ESX itself rather than any of the VM's running on the system

Developments

Upgrade to Virtual Centre v2.0.2

Should fix (to be confirmed)

• VM deployment / customisation bug where IP address not properly filled in on new VM

Does fix

• VC VMware service stops on SQL DB access prob (eg due to transient network prob), in v2.0.2 it fails so Windows knows to attempt to restart the service

Upgrade to ESX v3.0.2

• Requires VC v2.0.2 to be installed 1st
• DELL OpenManage v5.2 is supported (ONLY)

No experienced problems fixed, but test plants to be upgraded and new live plants to be installed with.

Resolved Problems

ESX NIC fail monitoring

No SNMP traps are sent if one of an ESX's network connections go down, therefore ESX resiliency can be lost without any notification being sent.

Monitoring script deployed

ESX HBA fail monitoring

No SNMP traps are sent if one of an ESX's SAN connections go down, therefore ESX resiliency can be lost without any notification being sent.
