Creating a shared NetApp SR over iSCSI

Device-config parameters for netapp SRs:

Parameter Name	Description	Optional?
target	the IP address or hostname of the NetApp server that hosts	no
	the SR
port	the port to use for connecting to the NetApp server that hosts	yes
	the SR. Default is port 80.
usehttps	specifies whether to use a secure TLS-based connection to	yes
	the NetApp server that hosts the SR [truefalse]. Default is
	false.
username	the login username used to manage the LUNs on the filer	no
password	the login password used to manage the LUNs on the filer	no
aggregate	the aggregate name on which the FlexVol is created	Required for
		sr_create
FlexVols	the number of FlexVols to allocate to each SR	yes
chapuser	the username for CHAP authentication	yes
chappassword	the password for CHAP authentication	yes
allocation	specifies whether to provision LUNs using thick or thin	yes
	provisioning. Default is thick
asis	specifies whether to use FAS Deduplication if available.	yes
	Default is false

Setting the SR other-config:multiplierparameter to a valid value adjusts the default multiplier attribute. By default XenServer allocates 2.4 times the requested space to account for snapshot and metadata overhead associated with each LUN. To save disk space, you can set the multiplier to a value >=

1.Setting the multiplier should only be done with extreme care by system administrators who understand the space allocation constraints of the NetApp filer. If you try to set the amount to less than 1, for example, in an attempt to pre-allocate very little space for the LUN, the attempt will most likely fail.

Setting the SR other-config:enforce_allocationparameter to true resizes the FlexVols to precisely the amount specified by either the multiplier value above, or the default 2.4 value.
