Enclosures

View information about the enclosures for storage systems. Enclosures are the metal structures in which various storage components are mounted, including control units, nodes, disks or drives, and power supplies.

Information about enclosures is available for storage systems, including systems that run IBM Storage Virtualize.

To view information about enclosures and their related resources, complete any of the following tasks:
Table 1. Viewing information about enclosures

View information about the enclosures that are associated with a storage system.

Depending on the type of storage system, the following information about an enclosure is shown:
  • Type of enclosure: Control, Expansion, or Storage
  • Machine Type model (MTM)
  • Physical location
  • I/O Group
  • The number of disks, drives, and slots that it contains
  • The number of nodes that it contains
  • The number of power supplies and canisters that it contains
  1. In the menu bar, go to Resources > Block Storage Systems.
  2. Right-click a storage system and select View Details.
  3. Under Internal Resources, click Enclosures.

View the disks in an enclosure.

Add enclosures to general groups.

Adding storage systems and their associated enclosures to general groups can be helpful when you want to receive alert notifications about changes to a group of logically related storage systems.
  1. In the menu bar, go to Resources > Block Storage Systems.
  2. Right-click a storage system and select View Details.
  3. Under Internal Resources, click Enclosures.
  4. Right-click an enclosure and select Add to General Group.
  5. Add the enclosure to an existing group or create a new group and click Save.
Use the information on the Enclosures page to complete these monitoring tasks:
  • View the physical site where the enclosure is located.
  • View the number of disks, drives, slots, nodes, power supplies, and canisters in the enclosure.
  • Understand the associations between the enclosure and its disks and nodes.
  • Identify the I/O group that is associated the enclosure.
  • Determine whether an enclosure is a control, expansion, or storage enclosure.
Information about enclosures is available for the following storage systems:
  • IBM Storage FlashSystem 9100
  • IBM Storage FlashSystem V9000
  • IBM Storage FlashSystem 900
  • SAN Volume Controller
  • IBM Storwize family
Additional information is provided about the following attributes of enclosures:
Acknowledged
Shows whether a user marked the status of an enclosure as acknowledged. An acknowledged status indicates that its status was reviewed and is either resolved or can be ignored. An acknowledged status is not used when the status of the associated storage system is determined.
For example, if an enclosure has an error status, the related storage system also shows an error condition. If the error status of the enclosure is acknowledged, it changes to Error-Acknowledged. This acknowledged status is then treated as normal, and is used in evaluating the overall condition of the storage system. In this case, if the other internal resources of the storage system are also normal, the storage system condition is considered normal.
Canisters
The number of power supply units (PSUs) in the enclosure. Each enclosure has at least 2 PSUs for redundancy.
I/O Group
The I/O group that is associated exclusively with the enclosure. For IBM Storage FlashSystem V9000, the storage enclosure is shared by all I/O groups.
Machine Type Model (MTM)
The 7-character identifier for the enclosure. The first 4 characters are the machine type and the last 3 characters are the model, such as 2076-112, 2145-24F, 9840-AE2. Typically, MTM is shown on labels on the front and rear of the enclosure.
Power Supplies
The number of power supply units (PSUs) in an enclosure. Each enclosure has at least 2 PSUs for redundancy.
Status
The status of an enclosure is determined by the most critical status of its native operation, power supplies, and canisters. For example, if an enclosure is operating normally, but one of its PSUs is offline, the overall status of the enclosure is Warning.
Use the status to determine the condition of the enclosure, and if any actions must be taken. Possible values are listed:
Normal (Online)
An enclosure, its PSUs, and its canisters are operating normally.
Warning
The enclosure is visible to the SAS network but not down both strands, or one of its canisters or PSUs is offline.
Error (Offline)
A managed enclosure is not visible to the SAS network, or its PSUs or canisters are offline. For troubleshooting information, see the IBM® Docs for the related storage system.
Type
The type of enclosure. Possible values are Control, Expansion, and Storage. The model of storage system determines the type of enclosure that is present.
