自動偵測主機實體

適用於UNIX的支援會自動偵測主機實體的組態、以執行部分命令。SnapDrive有些「午睡儲存設備」命令只需要主機實體名稱。在這些情況下、您不需要指定主機實體的類型。

下列命令可用於自動偵測：

"刪除"
《調整大小》
打造午睡功能
恢復快照
"網路快照連線"
《午餐清單》

當主機實體存在時、SnapDrive 適用於UNIX的現象會自動偵測主機實體的類型。在這種情況下、您只需要提供主機實體的名稱、而不需要指定類型。這個指令和一些「shorage」命令也只需要主機實體的名稱、您不需要指定類型。SnapDrive

自動偵測指令SnapDrive 需要更多時間才能執行、因為它會收集所有儲存資源的詳細資料。如果您想要更快的回應速度、請使用SnapDrive 適用於UNIX的指令功能來指定檔案規格。

您可以執行「SnapDrive 支援刪除儲存設備」命令、為儲存設備刪除作業啟用自動偵測。

範例1：

snapdrive storage delete host_dg my_fs -full

在範例中、會自動偵測到「host_dg」和「my_FS」。

範例2：

snapdrive storage delete mydg -fs myfs -full

在此範例中、系統會自動偵測到「mydg」磁碟群組。

您可以執行「SnapDrive 物件儲存區大小調整」命令、自動偵測儲存區大小調整作業。

例如：

[root@lnx197-132 ~]# snapdrive storage resize mydg23 -addlun -growby 10m
Auto detecting the type of filespec 'mydg23' in progress ... detected as disk group
        discovering filer LUNs in disk group mydg23...done
        LUN bart:/vol/voldm/mydg23-1_SdLun ... created

        mapping new lun(s) ... done
        discovering new lun(s) ... done.
        initializing LUN(s) and adding to disk group mydg23...done
Disk group mydg23 has been resized

您可以執行「SnapDrive 支援快照建立」命令來啟用快照建立作業的自動偵測功能。

例如：

root@lnx197-132 ~]# snapdrive snap create mydg22 mydg23 /mnt/mnt12 -snapname new_snap
Auto detecting the type of filespec 'mydg22' in progress ... detected as disk group
Auto detecting the type of filespec 'mydg23' in progress ... detected as disk group
Auto detecting the type of filespec '/mnt/mnt12 ' in progress ... detected as file system

Starting snap create /dev/mapper/mydg22, /dev/mapper/mydg23, /mnt/mnt12
  WARNING:  DO NOT CONTROL-C!
            If snap create is interrupted, incomplete snapdrive
                 generated data may remain on the filer volume(s)
                 which may interfere with other snap operations.
Successfully created snapshot new_snap on bart:/vol/voldm

        snapshot new_snap contains:
        disk group mydg22
        disk group mydg23
        disk group dg121 containing host volumes
                lv121 (filesystem: /mnt/mnt12)

您可以執行「SnapDrive 支援連結」命令、自動偵測快照連線作業。

例如：

[root@lnx197-132 ~]# snapdrive snap connect mydg22 xxx mydg23 yyy -snapname bart:/vol/voldm:snap_1
Auto detecting the type of filespec 'mydg22' in progress ... detected as disk group

Auto detecting the type of filespec 'yyy' in progress ...
        yyy does not exist - Taking yyy as a destination to fspec mydg23
 connecting mydg22:
        LUN copy mydg22_SdLun_0 ... created
                 (original: bart:/vol/voldm/mydg22_SdLun)

        mapping new lun(s) ... done

 connecting mydg23:
        LUN copy mydg23_SdLun_1 ... created
                 (original: bart:/vol/voldm/mydg23_SdLun)

        mapping new lun(s) ... done
        discovering new lun(s) ... done
        Importing xxx, yyy
Successfully connected to snapshot bart:/vol/voldm:snap_1
        disk group xxx
        disk group yyy

您可以執行「SnapDrive 還原快照」命令、啟用快照還原作業的自動偵測功能。

例如：

snapdrive snap restore bart:/vol/voldm/lun44 /mnt/fs3 fs5_SdDg/fs5_SdHv fs4_SdDg -snapname bart:/vol/voldm:toi_snap

        Auto detection of file_spec(s) in progress ...
               - 'bart:/vol/voldm/lun44' detected as LUN.
               - '/mnt/fs3' detected as file system.
               - 'fs5_SdDg/fs5_SdHv' detected as logical volume.
               - 'fs4_SdDg' detected as disk group.
        Starting to restore /dev/mapper/fs4_SdDg, /mnt/fs3, /dev/mapper/fs5_SdDg-fs5_SdHv, bart:/vol/voldm/lun44
         WARNING:  This can take several minutes.
           DO NOT CONTROL-C!
           If snap restore is interrupted, the filespecs
           being restored may have inconsistent or corrupted
           data.
       For detailed progress information, see the log file /var/log/sd-recovery.log
           Importing fs4_SdDg, fs3_SdDg, fs5_SdDg
           Successfully restored snapshot toi_snap on bart:/vol/voldm
       disk group fs4_SdDg containing host volumes
               fs4_SdHv (filesystem: /mnt/fs4)
       disk group fs3_SdDg containing host volumes
               fs3_SdHv (filesystem: /mnt/fs3)
       disk group fs5_SdDg containing host volumes
               fs5_SdHv (filesystem: /mnt/fs5)
       raw LUN: bart:/vol/voldm/lun44

由於檔案規格不正確、因此不支援自動偵測快照連線和快照還原作業。SnapDrive

您可以執行「SnapDrive 支援快照清單」命令、為快照清單作業啟用自動偵測。

例如：

root@lnx197-132 ~]# snapdrive snap list -snapname bart:/vol/voldm:snap_1

snap name                            host                   date         snapped

[root@lnx197-132 ~]# snapdrive snap list mydg23
