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 'xxx' in progress ... xxx does not exist - Taking xxx as a destination to fspec mydg22Auto detecting the type of filespec 'mydg23' 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 -------------------------------------------------------------------------------- bart:/vol/voldm:snap_1 lnx197-132.xyz.com Apr 9 06:04 mydg22 mydg23 dg121 [root@lnx197-132 ~]# snapdrive snap list mydg23 Auto detecting the type of filespec 'mydg23' in progress ... detected as disk group snap name host date snapped -------------------------------------------------------------------------------- bart:/vol/voldm:snap_1 lnx197-132.xyz.com Apr 9 06:04 mydg22 mydg23 dg121 bart:/vol/voldm:all lnx197-132.xyz.com Apr 9 00:16 mydg22 mydg23 fs1_SdDg bart:/vol/voldm:you lnx197-132.xyz.com Apr 8 21:03 mydg22 mydg23 bart:/vol/voldm:snap_2 lnx197-132.xyz.com Apr 8 18:05 mydg22 mydg23
