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

the SR

port the port to use for connecting to the NetApp server that hosts

the SR. Default is port 80.

yes

usehttps specifies whether to use a secure TLS-based connection to

the NetApp server that hosts the SR [true|false]. Default is

false.

yes

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

provisioning. Default is thick

yes

asis specifies whether to use FAS Deduplication if available.

Default is false

yes

Setting the SR other-config:multiplier parameter 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_allocation parameter to true resizes the FlexVols to

precisely the amount specified by either the multiplier value above, or the default 2.4 value.
