A while ago I noticed some color problems on my work display. It seemed to have problems with color gradients. I investigated a litttle and found information in the advanced display settings that my Dell-Display only supports only 6-Bit color depth.
Back than I found no clue what the problem could be. Except that at home with the same display I had no problems. Difference was: At home working with NVidia graphics card and at work with an Intel UHD 620 Chipset.
Some days ago I found at least two threads in the Intel forum with people with the same problem. They all have Dell displays and Intel UHD graphics. In one of the treads an Intel employee already said that the problem was found and a new driver will be released soon. As of now this did not happen but I will update this post than.
Update 2018-11-29: Yesterday a new driver was released wich fixes the problem. Beginning with driver version 220.127.116.1144 (UWD) full 8-Bit ist available again!
In vSphere 6.7U1 I could not update my ESXi-Hosts in my cluster because the new Remediation Pre-Check fails with the following error: “DRS should be enabled”
It also has a big red banner:
“Pre-check found problems that will block remediation. See details below. The blocking problems may have caused the pre-check to complete prematurely. Therefore, after fixing the problems, please re-run this pre-check.”
So Host remediation is blocked with error message: “Pre-check has found 2 issues that will block remediation”
Here are my work arrounds so far that I also posted on the relevant spiceworks thread:
1: use the old flex/flash-client. There is no pre-check
2: remove the esxi server from the cluster (just drag&drop the the server in question from the cluster to the datacenter). Outside of the cluster there is no DRS, so the pre-check works and update is not blocked anymore
But I think the second is the easiest way to do it.
I also opened a support request with VMware. I will keep you updated.
Today two of my ESXi 6.7 servers running on HP DL360p Gen8 didn’t behave as expected. VMotion and remote consoles quit with internal error.
In vspere syslog I found:
The ramdisk 'var' is full. As a result, the file /var/log/EMU/mili/mili2d.log could not be written.
On ESXi vdf -h revealed a full file system. The milid2.log was the problem and dumped the following errors:
CRITICAL:backend_init:OneConnect Adapter Not Found.
ERROR:rename all the configuration files!
ERROR:MILI_enumerate_elxiscsi:Failed to initialize User Init with status = 19
ERROR:MILI_enumerate_elx_nics:Failed to initialize USer Init with status = 19
ERROR:could not open device node /vmfs/devices/char/vmkdriver/be_esx_nic
In both servers no emulex hardware was installed. So I removed 3 packages form those ESXis with a reboot between each. The last one solved the problem!
