XenServer Administrator's Guide 4.1.0

Storage

Note

The Repair Storage Repository function within XenCenter can be used to retry the PBD creation

and plugging portions of the sr-create operation. This can be valuable in cases where the LUN

zoning was incorrect for one or more member servers in a pool when the SR was created. Correct

the zoning for the affected hosts and use Repair Storage Repository instead of removing and re-

creating the SR.

3.3.8. 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 in which the SR will

reside

username the login username used to manipulate the LUNs on the filer no

password the login password used to manipulate 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 per-SR yes

chapuser the username to be used during CHAP authentication yes

chappassword the password to be used during CHAP authentication yes

allocation this specifies whether thick or thin provisioning [thick | thin]; default is

thick

yes

asis this specifies whether to use A-SIS deduplication if available [true | false];

default is false

yes

To create a netapp SR use the following command.

xe sr-create host-uuid=<VALID_UUID> content-type=user \

name-label="Example shared NetApp SR" shared=true \

device-config:target=192.168.1.10 device-config:username=<admin username> \

device-config:password=<admin password> \

type=netapp

3.4. Managing Storage Repositories

This section covers various operations required in the ongoing management of Storage Repositories (SRs).

3.4.1. Destroying or forgetting a SR

You can destroy an SR, which will actually delete the contents of the SR from the physical media. Alterna-

tively an SR can be forgotten, which allows you to re-attach the SR, for example, to another XenServer

Host, without removing any of the SR contents. In both cases, the PBD of the SR must first be unplugged.

Forgetting an SR is the equivalent of the SR Detach operation within XenCenter.

1. Unplug the PBD to detach the SR from the corresponding XenServer Host:

xe pbd-unplug uuid=<PBD_UUID>
