Is there a way to view lower level Fibre Channel diagnostic
Is there a way to view lower level Fibre Channel diagnostic logs from the CLI? We are having an issue with some VMware hosts not getting a response to a PLOGI so they are not able to see any volumes from the Pure array on one of our fabrics. Other storage systems on the same fabric are working fine.New Pure Code site is live!
After many months of messing with some very old code, we have launched a revised site for the Pure Code Portal. It is much more minimalistic and cleaner than the old one, and we have plans to add our Code videos and Pure Employee website links in the near future. Have a look and feel free to leave a comment if you would like to see something on the site. https://code.purestorage.com/ Cheers, //MikeSome Fleet PowerShell code using Invoke-RestMethod
Hello fellow scripters! This script is a PowerShell script that uses native PowerShell cmdlets to do the tasks. It does not use the Pure Storage PowerShell SDK2. This is for folks who do raw API calls using automation packages, runbooks, and scripts. It is not intended to use in it's entirety, but rather to be used as code snippets and starters for your own scripts. The full script is available in this GitHub repository. This script will: Use native PowerShell (non-SDK) Invoke-RestMethod calls to the FlashArray API Authenticates an API Token user and gets the x-auth-token for requests Query a fleet and determine the fleet members Query fleet Presets & Workloads List fleet volumes and hosts (top X, configurable) Create a host, volume, and then connect the volume to the host on a member array. <# .SYNOPSIS Authenticates to Pure Storage FlashArray REST API and retrieves session token. .DESCRIPTION - Authenticates using API token. - Retrieves the x-auth-token from response headers for subsequent requests. - Dynamically queries the FlashArray for the latest available API version and uses it for requests. .PARAMETER Target Required. The FQDN or IP address of the FlashArray to target for REST API calls. .PARAMETER ApiToken Required.
