[libvirt] [PATCH 7/8] storage: Add startPool and stopPool for scsi backend

startPool creates the vHBA if it's not existed yet, stopPool destroys the vHBA. Also to support autostart, checkPool will creates the vHBA if it's not existed yet. --- src/storage/storage_backend_scsi.c | 64 ++++++++++++++++++++++++++++++++++++ 1 files changed, 64 insertions(+), 0 deletions(-) diff --git a/src/storage/storage_backend_scsi.c b/src/storage/storage_backend_scsi.c index 8166311..a9b96a3 100644 --- a/src/storage/storage_backend_scsi.c +++ b/src/storage/storage_backend_scsi.c @@ -634,6 +634,36 @@ getAdapterName(virStoragePoolSourceAdapter adapter) } static int +createVport(virStoragePoolSourceAdapter adapter) +{ + int parent_host; + + if (adapter.type != VIR_STORAGE_POOL_SOURCE_ADAPTER_TYPE_FC_HOST) + return 0; + + /* This filters either HBA or already created vHBA */ + if (virGetFCHostNameByWWN(NULL, adapter.data.fchost.wwnn, + adapter.data.fchost.wwpn)) + return 0; + + if (!adapter.data.fchost.parent) { + virReportError(VIR_ERR_XML_ERROR, "%s", + _("'parent' for vHBA must be specified")); + return -1; + } + + if ((parent_host = getHostNumber(adapter.data.fchost.parent)) < 0) + return -1; + + if (virManageVport(parent_host, adapter.data.fchost.wwnn, + adapter.data.fchost.wwpn, VPORT_CREATE) < 0) + return -1; + + virFileWaitForDevices(); + return 0; +} + +static int virStorageBackendSCSICheckPool(virConnectPtr conn ATTRIBUTE_UNUSED, virStoragePoolObjPtr pool, bool *isActive) @@ -695,10 +725,44 @@ out: return ret; } +static int +virStorageBackendSCSIStartPool(virConnectPtr conn ATTRIBUTE_UNUSED, + virStoragePoolObjPtr pool) +{ + virStoragePoolSourceAdapter adapter = pool->def->source.adapter; + + return createVport(adapter); +} + +static int +virStorageBackendSCSIStopPool(virConnectPtr conn ATTRIBUTE_UNUSED, + virStoragePoolObjPtr pool) +{ + virStoragePoolSourceAdapter adapter = pool->def->source.adapter; + int parent_host; + + if (adapter.type != VIR_STORAGE_POOL_SOURCE_ADAPTER_TYPE_FC_HOST) + return 0; + + if (!(virGetFCHostNameByWWN(NULL, adapter.data.fchost.wwnn, + adapter.data.fchost.wwpn))) + return -1; + + if ((parent_host = getHostNumber(adapter.data.fchost.parent)) < 0) + return -1; + + if (virManageVport(parent_host, adapter.data.fchost.wwnn, + adapter.data.fchost.wwpn, VPORT_DELETE) < 0) + return -1; + + return 0; +} virStorageBackend virStorageBackendSCSI = { .type = VIR_STORAGE_POOL_SCSI, .checkPool = virStorageBackendSCSICheckPool, .refreshPool = virStorageBackendSCSIRefreshPool, + .startPool = virStorageBackendSCSIStartPool, + .stopPool = virStorageBackendSCSIStopPool, }; -- 1.7.7.6
