(resolved) - Long boot time for ESXi hosts even after marking RDM LUNs as perennially-reserved

Long boot time for ESXi hosts even after marking RDM LUNs as perennially-reserved 

 

Error :

2019-09-17T19:47:44.846Z cpu39:65984)WARNING: celerity16fc: Task management abort failed, status:fffffffd
2019-09-17T19:47:44.849Z cpu21:66065)ScsiDeviceIO: 7916: Could not detect setting of QErr for device naa.600507680c8080dca80000000000058a. Error Timeout.
2019-09-17T19:48:02.959Z cpu28:66342)WARNING: ScsiCore: 1806: Invalid sense buffer: error=0x0, valid=0x0

Reason for the issue:

This is due to a known issue with storage stack. Some commands at boot time sense fail with reservation conflicts, timeouts and aborts.

 

Resolution:

At the moment, please try to use vmdk instead of RDM disks and the VMware engineering team looks like they are working on the fix.

Increasing the disk space for the VMware vCenter Server Appliance in vSphere 6.5, 6.7 and 7.0

  Purpose This article provides steps to increase the disk space of a specific VMDK for the vCenter Server Appliance 6.5, 6.7 and 7.0. With the introduction of Logical Volume Management (LVM) in vSphere 6.0 and continued support with vSphere 6.5, 6.7 and 7.0, the vCenter Server disks can be dynamically increased. List of VMDKs for a vCenter Server Appliance 6.5 - Size Mount point and Purpose Note : Resizing the root partition (VMDK1 listed in the KB above) is not supported on 6.5. Please see the vSphere 6.5 Release Notes for more information. Resizing root partition has been added to 6.7 and 7.0. List of VMDKs/Partitions for a vCenter Server Appliance 6.7 - Size Mount point and Purpose   List of VMDKs/Partitions for a vCenter Server 7.0 - Size Mount point and Purpose Note : This KB can be used for the situation like SEAT partition full or any other vCenter appliance partition full. ...

Cloning and converting virtual machine disks with vmkfstools

 Purpose This article provides information and instructions on the use of the vmkfstools command to convert virtual machine disks from one type to another. Resolution The vmkfstools command offers the ability to clone virtual machine content and also convert from one virtual machine disk ( .vmdk ) format into another. Note : The host operating system chosen to perform the conversion may not necessarily support running of virtual machines via the output format defined. vmkfstools maintains the possibility of exporting virtual disks for use in other VMware products which support alternative disk formats. To convert a virtual machine disk from one type to another: Shut down the virtual machine. Virtual machine disk files are locked while in-use by a running virtual machine. Log in to the VMware vSphere Management Assistant (v...
