In my latest project (API endpoint based on Symfony and api-platform), I have the task to optimize and automate CI/CD processes. As a result: here is super-simplified version of the resulting GitLab pipiline:

EMC Recover Point – how to recreate repository volume

We have to recreate repository volume of our RP but I could not find any guidance from EMC site. So I’m documenting my steps here for further usage:

Procedure overview:
On EMC storage:

Create about 6-8 GB LUN.
Present that LUN to storage group of RP nodes.

On RP appliances:
On last cluster member:

Detach RPA from cluster
Format repository volume
Reboot
Attach RPA to cluster

On each subsequent appliance:

Detach RPA from cluster
Select repository volume
Reboot
Attach RPA to cluster

This is a transcript of console sessions:

VLAN trunking in Hyper-V. Virtual switch to VM

1. get interface

PS C:\Windows\system32> Get-VMNetworkAdapter -VMName pfs3|fl adapterid,ipaddresses


AdapterId   : 258ffea6-f8ea-46af-a376-7c2b912fe68e
IPAddresses : {200.40.8.103, 200.40.8.100, fe80::215:5dff:fe05:a869}

AdapterId   : 39aeda55-19b3-403c-9c89-d0bf937a4930
IPAddresses : {200.40.19.243, 200.40.19.252, 200.40.19.17, fe80::215:5dff:fe05:a86a...}

2. set VLANs

PS C:\Windows\system32> Get-VMNetworkAdapter -VMName pfs4 |Where-Object {$_.adapterid -eq '5d488e8c-b066-4350-acfb-b4ccc
57a9ee7'}|Set-VMNetworkAdapterVlan -trunk -AllowedVlanIdList 1901-1924 -NativeVlanId 1924
