Identify the Multipath Devices

Using the 'format' command, identify the multipath devices

Make sure the path starts with /scsi_vhci

Create the ZPool

Use the device identified in Step 1 to create your ZPool. Create non-raid zpools, and let the RAID in

Purity take care of redundancy.

# zpool create bucket c4t624A9370A71D594A700C03C400014D1Fd0

Verify the existing ZPool:

root@t5140.ct.purestorage.com # zpool list
NAME     SIZE  ALLOC   FREE  CAP  HEALTH  ALTROOT
bucket  99.5G  8.96G  90.5G   9%  ONLINE  -

Check the status of "autoexpand"

root@t5140.ct.purestorage.com # zpool get autoexpand bucket
NAME    PROPERTY    VALUE   SOURCE
bucket  autoexpand  off     default

If the status is "off" we recommend you turn it on

root@t5140.ct.purestorage.com # zpool set autoexpand=on bucket


root@t5140.ct.purestorage.com # zpool get autoexpand bucket
NAME    PROPERTY    VALUE   SOURCE
bucket  autoexpand  on      local

NOTE: for zfs autoexpand feature to correctly work on Solaris 10U8, apply patch 147147-26

Creating the ZFS FileSystem

Solaris 10:

zfs create -o compression=off bucket/files

Solaris 11:

zfs create -o compression=off dedup=off bucket/files

NOTE: Please make sure you have compression and dedup set to off. The Everpure FlashArray will already provide back-end compression and dedup. Running this on the software layer will greatly impact performance.

Confirm that compression & dedup are off:

root@t5140.ct.purestorage.com # zfs get -r  compression bucket/files
NAME          PROPERTY     VALUE     SOURCE
bucket/files  compression  off       local

root@t5140.ct.purestorage.com # zfs get -r  dedup bucket/files
NAME          PROPERTY     VALUE     SOURCE
bucket/files  dedup        off       local

List your ZFS properties:

root@t5140.ct.purestorage.com # zfs list
NAME           USED  AVAIL  REFER  MOUNTPOINT
bucket        5.00G  92.9G  5.00G  /bucket
bucket/files    31K  92.9G    31K  /bucket/files

Snapshots

If you are making use of snapshots, You are not able to mount a snapshot created using Purity, due to it having a duplicate GUID. It is recommened that if you need to use snapshots of ZFS volumes, then use ZFS internal snapshot feature.
