Summary:PROBLEM TO BE SOLVED: To provide a storage control device, a storage control program, and a storage control method which can limit the influence caused by a path cutoff in association with restart of a redundantly constituted storage control device.SOLUTION: A storage control system 1 includes a storage device 2 and a server device 5. The storage device 2 includes a switching section 2s and storage control devices 4, 4d. The storage control device 4 includes a storage section 4a and a control section 4c. The storage section 4a stores path connection information 4b. When detecting a restart condition of the storage control device 4d, the control section 4c instructs the storage control device 4d to restart after switching a connection destination of a second port 5b in the switching section 2s from a second path 2b to the storage control device 4d to a third path 2c to the storage control device 4 on the basis of the path connection information 4b.SELECTED DRAWING: Figure 1 【課題】冗長構成されたストレージ制御装置の再起動に伴うパス切れによる影響を限定できる。【解決手段】ストレージシステム1は、ストレージ装置2とサーバ装置5を含む。ストレージ装置2は、切替部2sとストレージ制御装置4,4dを含む。ストレージ制御装置4は、記憶部4aと制御部4cを備える。記憶部4aは、パス接続情報4bを記憶する。制御部4cは、ストレージ制御装置4dの再起動条件を検出した場合に、パス接続情報4bにもとづいて切替部2sにおける第2ポート5bの接続先を、第2パス2bによるストレージ制御装置4dから第3パス2cによるストレージ制御装置4に切り替えた後、ストレージ制御装置4dに再起動を指示する。【選択図】図1
