Importing IBM i workloads into Skytap using direct transfer
We recommend using IBM Cloud Object Storage to import large VMs. For details, see Importing VMs or LPARS using IBM Cloud Object Storage.
You can also use IBM Backup, Recovery and Media Services (BRMS) to migrate the workload (user data) of an on-premises LPAR to Skytap.
Power A CPU architecture that supports IBM i, AIX, and Linux (on Power) in Skytap Cloud. VMs must enabled for your account to import IBM i LPARs.
x86 VM imports use a different process. For instructions about importing x86 The most common CPU architecture. x86 CPUs support Windows and Linux VMs in Skytap Cloud. VMs, see Importing x86 VMs using the VM Imports page.
Things to consider when you export an IBM i LPAR:
- Currently, the following are the versions of IBM i that Skytap supports:
- IBM i 7.2
- IBM i 7.3
- IBM i 7.4
Step 1: Create an IBM i VM in Skytap
Before you begin, create an environment in Skytap.
- Make sure the VM has the same OS version as the LPAR you’re backing up.
- Make sure the storage for the VM is large enough to hold the restored data.
Make sure the template has a large enough auxiliary storage pool (ASP) to hold the backup files.
For more information about auxiliary storage pools, see Working with auxiliary storage pools
Because a published service exposes a port to the public internet, we strongly recommend that you review Exposing and blocking public Internet access to VMs and Protecting a VM that is exposed to the internet or compromised.
Step 2: Export the workload to virtual tape
Follow the instructions in Backup, Recovery, and Media Services (BRMS), Backing up your entire system to back up your system to virtual tape.
Step 3: Transfer the workload to Skytap
Step 4: Restore the workload to the Skytap IBM i VM
For an overview of the restore process, see Restore the user data and related system data to the target system.
Restore the workload to the Skytap IBM i VM with the following steps:
Configure the workload backup
Create the image catalog:
CRTIMGCLG IMGCLG(‘VTAPOL01’) DIR(‘/myfs/backup/images’) CRTDIR(*NO) IMPORT(*YES) TYPE(*TAP)
Load image catalog entries:
- Load each image file as an entry one by one.
Load the image catalog:
LODIMGCLG IMGCLG(‘VTAPOL01’) DEV(TAPV01)
Restore the workload backup to the Skytap IBM i VM
Restore user profile data:
RSTUSRPRF USRPRF(*ALL) DEV(TAPV01)
Restore libraries and objects:
RSTLIB SAVLIB(*IBM) DEV(TAPV01) ENDOPT(*LEAVE) MBROPT(*ALL) ALWOBJDIF(*ALL)
RSTLIB LIB(*ALLUSR) DEV(TAPV01) ENDOPT(*LEAVE) ALWOBJDIF(*COMPATIBLE) FRCOBCVN(*NO)
RSTDLO DLO(*ALL) SAVFLR(*ANY) DEV(TAPV01) ENDOPT(*LEAVE)
RST DEV(‘/QSYS.LIB/TAPVO1.DEVD) OBJ((‘/*’) (‘/QSYS.LIB’ *OMIT) (‘/QDLS’ *OMIT)) ENDOPT(*REWIND) ALWOBJDIF(*ALL) OPTION(*NEW)
Restore private authorities to user profiles:
After the LPAR is restored to the Skytap VM
You may need to re-IPL (reboot) the Skytap VM a few times to make sure everything works correctly:
PWRDWNSYS *IMMED RESTART(*YES)
You may also need to re-balance auxiliary storage pools:
STRASPBAL ASP(1) TIMLMT(*NOMAX) TYPE(*CAPACITY)
