If a library is listed under the Unconfigurable header, it means that it does not meet the requirements for SGI InfiniteStorage Gateway configuration with DMF. For example, there may be an insufficient number of volumes. See “Secondary-Storage Requirements for DMF Simplified Configuration ” in Chapter 1.

If a COPAN MAID shelf is already formatted, it cannot be configured for DMF. You must unformat the shelf and return it to factory state, see “Returning a Shelf to Factory State”.

Caution: Unformatting a shelf will destroy any existing data.

If an expected user filesystem does not appear in the Configure DMF System page, ensure the filesystem is mounted with the dmi option according to the output of the mount(1) command.

For example, the following output shows that the dmfusr1 filesystem is ready for DMF use (mounted with the dmi option) but the dmfusr2 filesystem is not (mounted, but without the dmi option):

mis# mount | grep dmfusr
/dev/lxvm/user0 on /dmfusr1 type xfs (rw,noatime,dmi,mtpt=/dmfusr1)
/dev/lxvm/user1 on /dmfusr2 type xfs (rw,noatime,mtpt=/dmfusr2)

See “Create and Mount the User Filesystems” in Chapter 2.

DMF Manager denotes areas with problems by adding a yellow or red icon next to the component that is experiencing problems, depending upon severity. For example, Figure 7-1 shows that although DMF is still running, there are warnings that may require action (red icon). To investigate, hover the mouse over the shield icon to display pop-up help that describes the warning.

Figure 7-1. DMF Manager Showing Problems

For details, click the Alerts icon flag and select Show Alerts... or choose the following from the DMF Manager menu bar:

Either action will open the Alerts page, which displays the unacknowledged messages (similar to the Alerts page in the Management Center), but also provides more information about a particular alert if you select it and choose Help on this alert, as shown in Figure 5-5. For more information, see “Acknowledging DMF Alerts” in Chapter 5.

You can also use the following page to view daily activity reports (those containing critical log errors show red warning symbols):

If the Overview page indicates that there are problems, consult the DMF 6 Administrator Guide for SGI InfiniteStorage or call SGI Support.

Under circumstances such as the following, the migrated data will be unavailable:

If the MIS server is down, access to all data on the secondary storage is unavailable.

Powering on a COPAN MAID system requires a specific sequence of steps. You must call SGI Support for assistance.

To return a COPAN MAID shelf to unformatted factory state, use the SGI ov_copan unformat command. For more information, see the ov_copan(8) man page. If you did not use the ov_copan command to originally format the shelf, see the SGI COPAN 400 User Guide.
