Goal

Provide the instructions on how to grow a filesystem or LUN from the Pillar Axiom Storage Services Manager

"It is required to check OS limitations and procedures to resize LUN at OS level.

For example Windows has limitation for LUNs with MBR label over 2T. It is necessary to use GPT if the LUN size will be over 2T after resizing. Master boot record (MBR) disks use the standard BIOS partition table. GUID partition table (GPT) disks use unified extensible firmware interface (UEFI). One advantage of GPT disks is that you can have more than four partitions on each disk. GPT is also required for disks larger than 2 terabytes. But this conversion will destroy current data on disk. You need to take backup and restore after increasing the LUN size."

Solution

For R5:

How to grow a LUN:

1) Click on the Configure Tab in the top left context pane.

2) Click on LUNs

3) Highlight the LUN you want to modify on the right hand side.

4) Right click on the LUNs and select Modify LUN.

5) Change the Addressable Logical Capacity to the size you desire

6) Click OK

For R4 and below:

How to grow a filesystem:

1 Click the Storage icon in the top context pane.
2 Click the Filesystems link in the left navigation pane.
3 Select the filesystem that you want to modify.
4 Choose Modify Filesystem from the Actions drop-down list.
5 Click the Quality of Service tab.

Change the following parameter:

Maximum Capacity
Identifies the maximum capacity to which the logical volume can grow. For a
clone, this field identifies how much addressable space will be available.

Click OK.
In the GUI...the LUN will change from ONLINE to CONFIGURING. It will return to ONLINE once the
grow operation is complete.

NOTE: You will need to configure any host to accept the change in size as this operation is invisible to any
connected host(s)...

NOTE: You will need to configure any host to accept the change in size as this operation is invisible to any
connected host(s)...

***NOTE The LUN will be temporarily unavailable while the configuration changes complete. This can take up to 30 seconds.***

"For parameter definitions, see the following:

SAN LUN size
Minimum: 1 to 2 GB. The exact value depends on these factors

● Brick type (Fibre Channel or SATA)
● RAID geometry (RAID 5 or Distributed RAID)
● Strip size (1 MB or normal)
Maximum: System capacity
Note: All capacity values must be in increments of 1 GB.

Here Operating limits for Pillar Axiom SAN systems:
SAN LUNs Maximum n = 4095 visible for each system
                                            256 visible for each host
                                            4095 visible for each SAN Slammer


SAN LUN size Minimum: 1 to 2 GB. The exact value depends on these factors
Brick type (Fibre Channel, SATA, or SSD)
RAID geometry (RAID 5 or Pooled RAID 10)
Strip size (1 MB or normal)
Maximum = system capacity
Maximum capacity is unlimited for a logical volume if the Thin Provisioning license is installed.

For more details please consult Axiom system documentation:
Release 4.5 http://docs.oracle.com/cd/E28234_01/index.htm
Release 5.2 http://docs.oracle.com/cd/E27438_01/index.htm
Release 5.3 http://docs.oracle.com/cd/E29307_01/index.htm

The documentation also exists on the pilot as well and is available via the GUI for download."
