- How to Create a Local Storage Repository (CTX121313)
# cat /proc/partitions
# ll /dev/disk/by-id
Find the disk ID of the “sdb” or “cciss/c0d1”disk. The “scsi-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx” or “cciss-xxxxxxxxxxxxxxxxxxxxxxxxxx”format is what you need.
Create a Storage Repository (SR):
# xe sr-create content-type=user device-config:device=/dev/disk/by-id/<scsi-xxxxxxxxxxxxxxxxxxxxxxxxx> host-uuid=<host-uuid> name-label=”Local Storage 2” shared=false type=lvm-
Or –
# xe sr-create content-type=user device-config:device=/dev/disk/by-id/<cciss-xxxxxxxxxxxxxxxxxxxxxxxxx> host-uuid=<host-uuid> name-label=”Local Storage 2” shared=false type=lvm
xe task-list
xe task-cancel uuid=<task uuid>
