Dear all,
This is my first post, so hopefully this is in the right place. Any assistance is greatly appreciated.
ESXi 6.5
Host: Dell R910
Local Disks: Two 3.5tb , 3par 8000 Series, RAID 5
When I logged in today, I quickly realized that all of my VM's were down:
Datastore look this, 2 datastore missing.
On device are available
When I click one of my two devices
Partition
I'm really at a loss as to what to do. Any advice is greatly appreciated. If there is any other information that I can provide
Thank you
Siverian
script starts like this:
##### dd command for E10_AP_DEMO-flat.vmdk #####
#####
#####
##### enter devicename for the VMFS-partition in the next line
IF=
#####
#####
##### check name for the outputfile - usually name-flat.vmdk - in the next line
OF=E10_AP_DEMO-flat.vmdk
#####
##### run this command in a directory that has enough free space for the vmdk-file
#####
#####
CMD="dd if=$IF of=$OF conv=notrunc bs=1M "
#####
$CMD seek=66536 count=1 skip=1375017 # E10_AP_DEMO-flat.vmdk fragment=14537#
$CMD seek=66537 count=1 skip=1375020 # E10_AP_DEMO-flat.vmdk fragment=14538#
$CMD seek=66538 count=1 skip=1375049 # E10_AP_DEMO-flat.vmdk fragment=14539#
....
obviously it will not work if you specify
IF=naa.number
use full path for the decive such as
IF=/dev/disks/naa,blablabla:1
Any changes on the storage side?
log a call with VMware Support, that will make things lot quicker to get a definitive answer since you are dealing data.
No changes on Storage, When i Reboot the server is what all these happens
I saw something similar with a 3par, and it required a rescan on the FC adapters to make d´the daatstores available again.
If that doesn't help, please run
esxcli storage vmfs snapshot list
from the command line to see whether the LUNs were detected as so called Snapshot LUNs.
In that case you may follow the steps in the "Command line" section of https://kb.vmware.com/s/article/1011387 to mount the datasatores again.

Did you try the first script I send you ?

Ulli
the query did not return any information
[root@Esxi65:~] esxcli storage vmfs snapshot list
[root@Esxi65:~]
i did not manage to run the script, it give me the error on failing to read the device name

First missing VM is back and running.
Let me know if you want the rest of them .....
Ulli
So you lost interest ?
what a waste of time ....
I wll delete the other scripts in an hour
Ulli
Don't delete the scripts please i need them badly
Actual size for E10_DB_01 is 2,089,072,092,774 Byte but descriptor vmdk is 2,089,070,624,768 Byte, so descriptor is 1.4MB less. Actual size for E10_AP_PILOT is 150,323,855,360 Byte but descriptor vmdk is 150,322,806,784 Byte, so is 1MB less. please can you help me to extract 2 scripts for the missing MBs?
Recovery of three VMs was successful.
continuum you are an absolute genius,I have no idea how you did to create the recovering script from my devices but I could be more thankful. So far, we were able to recover my 3 Vms. I learned a lot of best practice for my environment . I really appreciate your patience when working with me on this!
As far as a solution to the problem, I think continuum would be able to better explain it.
Thank you so much again!
