【IBM Cloud Block Storage 】複製ボリュームのTarget IPが同じでiSCSIディスカバリできない場合の対処

Posted at

ケース

Block Storageのボリューム複製方法はいくつかあるが、以下の複製を実施。
https://cloud.ibm.com/docs/BlockStorage?topic=BlockStorage-migratestorage

複製元と先で、Target IPが同じとなり、
# iscsiadm -m discovery -t sendtargets -p <ip-value-from-IBM-Cloud-console>
によってディスカバリ不可。
(/dev/mapper/が認識されない。)

対処法

iscsiadm -m session --rescan
にてiSCSI再スキャン実施により、/dev/mapper/に複製先ボリュームのデバイスが出現。
