Increasing the Flash Size on a vSphere Hypervisor

ArubaOS enables you to increase the size of your flash to ensure that the flash is hosted on a separate disk. By doing this you can move to a hard disk with higher storage capacity for flash with minimal impact. Follow the steps below to increase the size of the flash on the Mobility Master Virtual Appliance.

1. Power down the VM Virtual Machine. A VM is an emulation of a computer system. VMs are based on computer architectures and provide functionality of a physical computer..

2. Right click the VM Virtual Machine. A VM is an emulation of a computer system. VMs are based on computer architectures and provide functionality of a physical computer. in the vSphere client and click Edit Settings.

3. Click Add in the Virtual Machine Properties window.

4. Click Hard Disk in the Add Hardware window and click Next.

5. Select Create a new virtual disk and click Next.

6. Enter a value of the desired disk size and select Thick Provision Lazy Zeroed. Click Next.

7. Click Next in the Advanced Options window and click Finish.

8. Power on the VM Virtual Machine. A VM is an emulation of a computer system. VMs are based on computer architectures and provide functionality of a physical computer. and ArubaOS will migrate data from the old hard disk to the new one.

9. Confirm if the newly added Hard disk 3 is used by ArubaOS. The Hard disk 3 will be listed as /dev/sdc1 and if old hard disk is in use, it will be listed as /dev/sdb1. If the OVF Open Virtualization Format. OVF is a specification that describes an open-standard, secure, efficient, portable and extensible format for packaging and distributing software for virtual machines. file only contains a single hard disk it be listed as /dev/sda3.

10. If the new Hard disk 3 is working as expected, the older hard disk can be removed from the VM Virtual Machine. A VM is an emulation of a computer system. VMs are based on computer architectures and provide functionality of a physical computer. and deleted from disk of the vSphere server.

ArubaOS recognizes a maximum number of three disks. When a new disk is added, ensure to have a higher Virtual SCSI Small Computer System Interface. SCSI refers to a set of interface standards for physical connection and data transfer between a computer and the peripheral devices such as printers, disk drives, CD-ROM, and so on. device node number, else the disk names will be re-ordered and the data migration process might fail. If an unused disk is removed, data will be migrated upon a reboot or power up.
