Fibre Channel

1.0.0.12

November 24, 2020

Changes from the previous version 1.0.0.11:

  • Change the lower value in the range of rw_timeout from 30 to 10.
  • Add the 'x' bit to the permissions of the pre_d file. This makes it so that if PURE disks exist the ODM can't be removed.
  • Change the default value of reset_delay from 2 to 0.

Fibre Channel

1.0.0.11

May 22, 2019

Requires AIX 6.1 TL9, AIX 7.1 TL3 or AIX 7.2.

This update:

  • Sets the shortest_queue algorithm as the default path selection policy mechanism.
  • Includes the attribute lbp_enabled,(although not visible) necessary for space reclamation in AIX now that they support in the AIX filesystem.
  • Introduces attribute timeout_policy with the default policy to fail_path.
  • Identifies the attributes that can be concurrently modified.

Additionally, 1.0.0.10 allows installing on top of the previous versions without having duplicated attributes.

If the customer wants to confirm the value of lbp_enabled, they can query the ODM with:

$ odmget -q "uniquetype = 'disk/fcp/puredisk' and attribute=lbp_enabled" PdAt

1.0.0.11 fixed a checksum issue for pure.cat (PURE-147896).
