Hello, 

 

The Show Storage is similar to the df command on linux :

 

Filesystem      Size  Used Avail Use% Mounted on
/dev/loop0       18G   15G  2.5G  86% /
none            4.0K     0  4.0K   0% /sys/fs/cgroup
udev            483M  4.0K  483M   1% /dev
tmpfs            99M  1.4M   97M   2% /run
none            5.0M     0  5.0M   0% /run/lock
none            492M  1.8M  490M   1% /run/shm
none            100M   20K  100M   1% /run/user
/dev/sda3       167G  157G  9.9G  95% /host

As far as I can see, both disks are to storage the boot images sor for the Mobility Master.

/dev/sdb1 this is the files available in directory(we can check this by using the command: #dir)
/dev/sdb5 this is boot partition 0:0
/dev/sdb6 this is boot partition 0:1

What are you trying to do?

Re: Aruba MM HD Size

I want to understand the file system on the MM before I migrate all my enviroment from 6.5 to 8.0. According to the ArubaOS requiments to run a MM-500 I need 8GB disk and for a MM-5K I would need 16GB so I want to undersdtand how the capcity will be used.

Re: Aruba MM HD Size

Check the latest AOS 8.1 installation guide, I believe the disk size requirements changed (you are likely looking at the AOS 8.0 sizing numbers, which were increased for AOS 8.1+).

 

MM-VA-500 = 8GB Disk

MM-VA-1K = 32GB

MM-VA-5K = 64GB

MM-VA-10K = 128GB

 

As far as the disks setup on the ESX host, there are two hard disks created. One will be 4GB which is Hard Disk 1 and is where the base OS / firmware is for subsequent images (think wr erase all). The other Hard Disk 2 will be the live disks where the two partitions, flash, etc will be.

Re: Aruba MM HD Size

Thanks for the clarification. So can I delete the 4GB HD1 on my ESXi host then?

Re: Aruba MM HD Size

No, that HD is your backup partition should you need to migrate or recover from a wr erase. Everything on the ESX VM is required and should not be deleted.
