<p class="shortdesc">To facilitate the classification, search, and aggregation of EBS disks, you can identify an EBS disk by adding a tag to it. </p> <section class="section context"><div class="tasklabel"><h2 class="doc-tairway">About this task</h2></div> <p class="p">Tags of EBS disks are a set of Key-Value pairs. Each tag consists of a pair of Key-Value. A key can correspond to multiple values. Each EBS disk can be bound with multiple tags. There must be only one key of any tag of each instance, and tags with the same keys will be overwritten. </p> <p class="p">If there is no resource bound to a tag after it has been unbound, the tag will be deleted automatically. </p> <p class="p">Tag information in each region of Ping An Cloud is interconnected. A tag created in one region can be seen in other regions. </p> </section> <section><div class="tasklabel"><h2 class="doc-tairway">Procedure</h2></div><ol class="ol steps"><li class="li step stepexpand"> <span class="ph cmd">Log in to the <a class="xref" href="/console/ecs/overview" target="_blank">ECS Console</a>.</span> </li><li class="li step stepexpand"> <span class="ph cmd">In the left navigation pane, click <span class="ph menucascade"><span class="ph uicontrol">Block Storage</span><abbr title="and then"> > </abbr><span class="ph uicontrol">Disk</span></span>. </span> </li><li class="li step stepexpand"> <span class="ph cmd">On the <span class="keyword wintitle">Disk Management</span> page, find the disk for which you want to edit the tag, and then click <span class="ph menucascade"><span class="ph uicontrol"><img class="image" id="editlabel__image_bzw_hvm_slb" src="https://obs-cn-shanghai.yun.pingan.com/pcp-portal/20200707171848-178b1c519895.png"></span><abbr title="and then"> > </abbr><span class="ph uicontrol">Edit Tag</span></span> in the operation column.</span> </li><li class="li step stepexpand"> <span class="ph cmd">On the <span class="keyword wintitle">Edit Tag</span> page, enter the key and value in the <span class="ph uicontrol">Bind Key-Value</span> field, and then click <span class="ph uicontrol">Add</span>. </span> <div class="itemgroup info"> <img class="image" id="editlabel__image_xhz_tqn_slb" src="https://obs-cn-shanghai.yun.pingan.com/pcp-portal/20200707171848-108b4e169f46.png" width="800"> </div> </li><li class="li step stepexpand"> <span class="ph cmd">After that, click <span class="ph uicontrol">Confirm</span>.</span> </li></ol></section> <section class="section result" id="editlabel__result_l1n_vqn_slb"><div class="tasklabel"><h2 class="doc-tairway">Results</h2></div> <p class="p">You can view the added tag in the tag area of <span class="ph uicontrol">Disk Information</span>. </p> <img class="image" id="editlabel__image_agn_grn_slb" src="https://obs-cn-shanghai.yun.pingan.com/pcp-portal/20200707171848-1dafd89f974b.png" width="800"> <p class="p">When searching for an EBS disk, you can select the tag.
