如何升级 Unity OE 代码
方法 1:使用 Unisphere GUI
1.以“管理员或同等用户”的身份登录 Unisphere 后,转到 "settings" 菜单
2.导航到 “软件和许可证 > 软件升级”
注意:
在此处,它显示您当前使用的 Unity OE 版本以及以下 3 个选项
- Perform Health Checks
- Start Upgrade
- Download New Software
3 .准备好开始升级时。
- 从 https://www.dell.com/support/home/en-us/product-support/product/unity-family/drivers 下载新软件文件
- 执行运行状况检查(可选,因为它也将在 “Start Upgrade” 向导中完成)
- 单击 "Start Upgrade" 以启动升级向导。
4.升级前的
"Perform Health Checks” 选项提醒:
如果出现警告,先解决它们,然后再执行升级。
5.上传从 https://www.dell.com/support/home/ 站点下载的 Unity OE 升级文件。

上传 Unity OE 文件后其应怎样:提醒:
单击 "Next” 按钮后,系统将准备该文件以进行升级。这可能需要大约 5-10 分钟。
提醒:如果在此步骤后取消升级,请确保从主 SP 上的 /var/tmp/upgrade 中删除映像。使根 FS 保持高使用率可能会导致 SP 崩溃。
6.下一步是决定何时重新启动 SP。如果选择此选项,将在执行升级时一次重新启动一个 SP。如果未选中,您可以稍后自行重新启动 SP(通过“Resume Upgrade”)。默认设置是自动选择以允许 Unity 根据需要重新启动 SP。
7.查看摘要页面,并确保您看到新版本的上一版本
提醒:
请阅读有关何时进行升级的建议。
8.单击 "Finish" 按钮以开始 Unity OE 升级。
如果在升级过程中出现任何错误,请参阅相关消息和补救信息以“重试”。如果有任何问题,请联系您的服务提供商。
在升级过程中,由于 SP 重新启动、空间不足等原因,环境可能会显示错误或警报。
9.Unity OE 升级完成后,重新加载 Unisphere。新代码现在应显示在 "System View"中的 "Summary” 选项卡中。
Method 2 : Using Command Line (uemcli) 1) Download the image first (We can use any clients that supports uemcli like windows, linux or even unity console itself. If Unity console is used, the image need to be copied to peer SP) Below is an example for a complete upgrade by uemcli. a) SSH Login to the array using service account [Example: SPA is managing SP and SPB is peer SP ] b) Get the upgrade image file using winSCP or sftp to /cores/service(Example: Unity-4.1.2.9257522.tgz.bin.gpg ) For OE 4.5+: /cores/service/user/ c) Copy the image to peer SP : scp /cores/service/Unity-4.1.2.9257522.tgz.bin.gpg peer:/cores/service For OE 4.5+: scp /cores/service/user/Unity-4.1.2.9257522.tgz.bin.gpg peer:/cores/service/user d) Delete the image from local SP (SPA in this example) : rm /cores/service/Unity-4.1.2.9257522.tgz.bin.gpg For OE 4.5+: rm /cores/service/user/Unity-4.1.2.9257522.tgz.bin.gpg e) ssh to peer SP : ssh peer 2) Upload the image : C:\> uemcli -d <unity_management_ip> -u admin -securePassword -upload -f c:\data\Unity-4.2.0.9392909.tgz.bin.gpg upgrade Password: Uploaded 2.01 GB of 2.01 GB [ 100%] -PROCESSING- Operation Completed successfully If the file was uploaded to Unity via SCP/SFTP: uemcli -d <unity_management_ip> -u admin -securePassword -upload -f /cores/service/user/Unity-4.1.2.9257522.tgz.bin.gpg upgrade Note: If the upgrade is cancelled after this step, make sure the image is deleted from /var/tmp/upgrade on the primary SP. Leaving the root FS in high usage could lead to SP panic. 3) Verify the image candidate ID C:\> uemcli -d 10.0.0.1 -u admin -securePassword /sys/soft/ver show Password: 1: ID = INST_1 Type = installed Version = 4.1.1.9138882 Release date = 2017-02-09 14:30:02 2: ID = CAND_1 Type = candidate Version = 4.2.0.9392909 Release date = 2017-06-28 11:28:31 4) Create (start) the upgrade (optional to specify pause before reboot, if not given full upgrade will start immediately): C:\> uemcli -d 10.0.0.1 -u admin -securePassword /sys/soft/upgrade create -candId CAND_1 -pauseBeforeReboot 5) Monitor the upgrade : C:\> uemcli -d 10.0.0.1 -u admin -securePassword /sys/soft/upgrade show -detail 6) Resume the upgrade if pause before reboot is given or any health checks failed (like Replication session not paused earlier) : C:\> uemcli -d 10.0.0.1 -u admin -securePassword /sys/soft/upgrade resume 7) Verify after it completes 04:48:27 service@(none) spb:~> uemcli /sys/soft/ver show -detail 1: ID = INST_1 Type = installed Version = 4.2.0.9392909 Release date = 2017-06-28 11:28:37 Image type = Reboot required = Pause allowed = Image filename = 04:48:36 service@(none) spb:~> uemcli /sys/soft/upgrade show -detail 1: Status = completed Creation time = 2017-08-03 03:30:10 Elapsed time = 55m 36s Estimated time left = Progress = Percent complete = 100%
추가 정보
DELL EMC 建议在低生产期间执行 Unity OE 代码升级。升级期间不应有任何 DU/DL,但是在升级期间可能会降低速度并提高 CPU 占用率。
在升级之前,核心/服务应至少具有 5GB 可用空间。通常,删除旧数据收集是释放该空间的最佳方式。
如果升级到 4.5 或 4.5.1,请参阅知识库文章
