VSAN DISK FAULT

FAULT DISK VSAN

First Step:

We need to Update the firmware for the Raid Controller and UCS VIC:

Cisco 12G SAS Modular Raid Controller

Runninng:

lsi-mr3                                         7.703.19.00-1OEM.670.0.0.8169922    

Recommended:

Driver Version                             7.706.09.00-1OEM.670.0.0.8019320

UCS VIC 1227 10-Gbps 2 port CNA SFP+(Cisco)

Runninng:

nenic                          1.0.25.0-1OEM.670.0.0.8169922

Recommended:

Driver Version           1.0.27.0-1OEM.670.0.0.8169922 nenic

ESXi 6.7 nenic 1.0.27.0 NIC

https://my.vmware.com/web/vmware/details?downloadGroup=DT-ESXI67-CISCO-NENIC-10270&productId=745

VMware ESXi 6.7 lsi-mr3 7.706.09.00-1OEM:

https://my.vmware.com/web/vmware/details?downloadGroup=DT-ESXI67-AVAGO-LSI-MR3-77060900-1OEM&productId=745

Drivers update guide:

https://www.cisco.com/c/en/us/support/docs/servers-unified-computing/ucs-manager/116349-technote-product-00.html

After that you need to execute the next command:

VMware kB: https://kb.vmware.com/s/article/2144936 

Configure the vSAN IO timeout settings.

esxcfg-advcfg -s 100000 /LSOM/diskIoTimeout

esxcfg-advcfg -s 4 /LSOM/diskIoRetryFactor

Notes:

• This is not required if you are running ESXI 6.0 patch ESXi600-201608001 or later.
• These commands must be run on each ESXi host in the vSAN cluster.
• These commands are effective immediately. No reboot is required.
• These commands result in persistent changes and remains configured across reboots.

Round Robin Multipath Policy

Hello Guys,

In this post I will show you how to set round robin multipath policy:

First you need to know the actual Multipath Policy:

PS /Users/vicentemeneses> Get-VMhost b200m3-2-9-192g-18.vmccloud.net | Get-ScsiLun -LunType disk                                                                                                                                                

CanonicalN ConsoleDeviceName              LunType         CapacityGB MultipathPolicy 

ame                                                                                  

---------- -----------------              -------         ---------- --------------- 

        

naa.600... /vmfs/devices/disks/naa.600... disk             2,048.000 RoundRobin             

naa.600... /vmfs/devices/disks/naa.600... disk             2,048.000 RoundRobin          

naa.600... /vmfs/devices/disks/naa.600... disk             5,120.000 RoundRobin           

naa.600... /vmfs/devices/disks/naa.600... disk             2,048.000 RoundRobin              

naa.600... /vmfs/devices/disks/naa.600... disk             2,048.000 RoundRobin            

naa.600... /vmfs/devices/disks/naa.600... disk             2,752.000 RoundRobin      

naa.600... /vmfs/devices/disks/naa.600... disk             2,048.000 RoundRobin      

naa.600... /vmfs/devices/disks/naa.600... disk            55,807.822 RoundRobin              

naa.600... /vmfs/devices/disks/naa.600... disk            32,768.000 RoundRobin      

naa.600... /vmfs/devices/disks/naa.600... disk             5,120.000 RoundRobin             

naa.600... /vmfs/devices/disks/naa.600... disk             5,120.000 RoundRobin      

naa.600... /vmfs/devices/disks/naa.600... disk             5,120.000 RoundRobin      

naa.600... /vmfs/devices/disks/naa.600... disk             2,048.000 RoundRobin             

naa.600... /vmfs/devices/disks/naa.600... disk             2,048.000 RoundRobin  

And After that you need to set the multipath policy:

PS /Users/vicentemeneses> Get-VMhost b200m3-2-9-192g-18.vmccloud.net | Get-ScsiLun -LunType disk |Set-ScsiLun -MultipathPolicy "RoundRobin" 

CanonicalN ConsoleDeviceName              LunType         CapacityGB MultipathPolicy 

ame                                                                                  

---------- -----------------              -------         ---------- --------------- 

naa.600... /vmfs/devices/disks/naa.600... disk             2,048.000 RoundRobin

Delete Multiple Snapshot Instances with PowerCLI

Hello Guys,

In this post I'm going to show how to delete multiple snapshot instances in VMware vSphere:

1.  You need to construct a PowerCLI query:

             PS /Users/vicentemeneses> 

             $snapshotprd=Get-Cluster C3-PRODUCTION |Get-    VM |Get-Snapshot

             The query above gets all the snapshots in the virtual machines and store the result in a                         variable called $snapshotprd

      2.   After that, you need to check the variable information, just type the variable in PowerCLI:

            PS /Users/vicentemeneses> $snapshotprd

      3.  Delete all the snapshots, take care of the Veeam backup snapshots  

           PS /Users/vicentemeneses> Remove-Snapshot -Snapshot $snapshotmgmt                                                                                       -RemoveChildren
