+Purpose::
+  Provides primary mirrors and additional storage in PHX2
+
+== Description
+
+At present we have three netapps in our infrastructure. One in TPA, RDU
+and PHX. For purposes of visualization its easiest to think of us as
+having 4 netapps, 1 TPA, 1 RDU and 1 PHX for public mirrors. And an
+additional 1 in PHX used for additional storage not related to the
+public mirrors.
+
+== Public Mirrors
+
+The netapps are our primary public mirrors. The canonical location for
+the mirrors is currently in PHX. From there it gets synced to RDU and
+TPA.
+
+=== Snapshots
+
+Snapshots on the PHX netapp are taken hourly. Unfortunately the way it
+is setup only Red Hat employees can access this mirror (this is
+scheduled to change when PHX becomes the canonical location but that
+will take time to setup and deploy). The snapshots are available, for
+example, on wallace in:
+
+....
+/var/ftp/download.fedora.redhat.com/.snapshot/hourly.0
+....
+
+== PHX NFS Storage
+
+There is a great deal of storage in PHX over NFS from the netapp there.
+This storage includes the public mirror. The majority of this storage is
+koji however there are a few gig worth of storage that goes to wiki
+attachments and other storage needs we have in PHX.
+
+You can access all of the nfs share shares at:
+
+....
+batcave01:/mnt/fedora
+....
+
+or:
+
+....
+ntap-fedora-a.storage.phx2.redhat.com:/vol/fedora/
+....
+
+=== Access
+
+____
+The netapp is provided by RHIS and as a result they also control access.
+Access is controlled by IP mostly and some machines have root squashed.
+Worst case scenario if batcave01 is not accessible, just bring another
+box up under its IP address and use that for an emergency.
+____
+
+=== Snapshots
+
+There are hourly and nightly snapshots on the netapp. They are available
+in:
+
+....
+batcave01:/mnt/fedora/.snapshot
+....
+
+== iscsi
+
+We have iscsi deployed in a number of locations in our infrastructure
+for xen machines. To get a list of what xen machines are deployed with
+iscsi, just run lvs:
+
+....
+lvs /dev/xenGuests
+....
+
+Live migration is possible though not fully supported at this time.
+Please shut a xen machine down and bring it up on another host. Memory
+is the main issue here.
+
+=== Updating LVM
+
+iscsi is mounted all over the place and if one xen machine creates a
+logical volume the other xen machines will have to pick up those
+changes. To do this run:
+
+....
+pvscan
+vgscan
+lvscan
+vgchange -a y
+....
+
+=== Mounting ISCSI
+
+On reboots sometimes the iscsi share is not remounted. This should be
+automated in the future but for now run:
+
+....
+iscsiadm -m discovery -tst -p ntap-fedora-b.storage.phx2.redhat.com:3260
+sleep 1
+iscsiadm -m node -T iqn.1992-08.com.netapp:sn.118047036 -p 10.5.88.21:3260 -l
+sleep 1
+pvscan
+vgscan
+lvscan
+vgchange -a y
+....
