How to Add File Systems to an Online HAStoragePlus Resource

When you add a file system to an HAStoragePlus resource, the HAStoragePlus resource treats a local file system differently from a global file system.

For information about the AffinityOn extension property, see Synchronizing the Startups Between Resource Groups and Disk Device Groups.

  1. On one node of the cluster, become superuser.

  2. In the /etc/vfstab file on each node of the cluster, add an entry for the mount point of each file system that you are adding.

    For each entry, set the mount at boot field and the mount options field as follows:

    • Set the mount at boot field to no.

    • If the file system is a global file system, set the mount options field to contain the global option.

  3. Retrieve the list of mount points for the file systems that the HAStoragePlus resource already manages.


    # scha_resource_get -O extension -R hasp-resource -G hasp-rg \
FileSystemMountPoints
    -R hasp-resource

    Specifies the HAStoragePlus resource to which you are adding file systems

    -G hasp-rg

    Specifies the resource group that contains the HAStoragePlus resource

  4. Modify the FileSystemMountPoints extension property of the HAStoragePlus resource to contain the following mount points:

    • The mount points of the file systems that the HAStoragePlus resource already manages

    • The mount points of the file systems that you are adding to the HAStoragePlus resource


    # scrgadm -c -j hasp-resource -x FileSystemMountPoints="mount-point-list"
    -j hasp-resource

    Specifies the HAStoragePlus resource to which you are adding file systems

    -x FileSystemMountPoints="mount-point-list"

    Specifies a comma-separated list of mount points of the file systems that the HAStoragePlus resource already manages and the mount points of the file systems that you are adding

  5. Confirm that you have a match between the mount point list of the HAStoragePlus resource and the list that you specified in Step 4.


    # scha_resource_get -O extension -R hasp-resource -G hasp-rg \
 FileSystemMountPoints
    -R hasp-resource

    Specifies the HAStoragePlus resource to which you are adding file systems

    -G hasp-rg

    Specifies the resource group that contains the HAStoragePlus resource

  6. Confirm that the HAStoragePlus resource is online and not faulted.

    If the HAStoragePlus resource is online and faulted, validation of the resource succeeded, but an attempt by HAStoragePlus to mount a file system failed.


    # scstat -g
Example 2–3 Adding a File System to an Online HAStoragePlus Resource

This example shows how to add a file system to an online HAStoragePlus resource.

The example assumes that the /etc/vfstab file on each cluster node already contains an entry for the file system that is to be added.


# scha_resource_get -O extension -R rshasp -G rghasp FileSystemMountPoints
STRINGARRAY
/global/global-fs/fs1
# scrgadm -c -j rshasp \
-x FileSystemMountPoints="/global/global-fs/fs1,/global/global-fs/fs2"
# scha_resource_get -O extension -R rshasp -G rghasp FileSystemMountPoints
STRINGARRAY
/global/global-fs/fs1
/global/global-fs/fs2
# scstat -g
