It is critical that if you update one component that you also update other components to the
matching levels (see the readme file for the release to which you are upgrading). You must
not
run a mismatched set.
Linux environments
For Linux environments, it is critical that you have the correct kernel version installed in order
to install the RDAC driver. RDAC is still the preferred failover driver for Linux systems. The
Storage Manager for Linux readme lists the supported kernel versions. See Figure 7-4 for an
example with SM10.60.

7.1.4 Updating the DS5000 storage subsystem host software
In this section, we discuss updating the DS5000 storage subsystem host software on a
Windows and Linux host server, and we present a specific sequence to follow.
----------------------------------------------------------------------------
| OS | Version | RDAC |
| | | |
|----------------------|--------------------------|--------------------------|
| LoP-Redhat 4 | 2.6.18-128.El | Yes(note a) |
| update 7 (RHEL4-u7)| |rdac-LINUX-09.03.0B05.0214|
|----------------------|--------------------------|--------------------------|
| LoP-Redhat 5 | 2.6.18-128.EL5 | Yes (note b) |
| update 3 (RHEL5-u3)| |rdac-LINUX-09.03.0C05.0214|
|----------------------------------------------------------------------------|
| LoP-SLES 9 Service | 2.6.5-7.308-smp | Yes(note a) |
| Pack 4 (SLES9-SP4) | |rdac-LINUX-09.03.0B05.0214|
|----------------------|--------------------------|--------------------------|
| LoP-SLES 10 Service | 2.6.16.60-smp | Yes(note a) |
| Pack 2 (SLES10-SP2)| |rdac-LINUX-09.03.0C05.0214|
|----------------------|--------------------------|--------------------------|
| LoP-SLES 11 | 2.6.27.19-5-default | Yes (note a) |
| | |rdac-LINUX-09.03.0C05.0214|
----------------------------------------------------------------------------
Notes:
a. The redundant failover/failback capability is supported by the IBM
DS Storage Manager Linux RDAC driver versions 9.03.0B05.0214 for SLES 9,
RedHat 4 and SLES 10 (2.6 kernels), and 9.03.0C05.0214 for Redhat 5.x and
SLES10 SP1 and greater and SLES 11.
b. Redhat 5.0 is supported by the Storage Manager client only.
Important: Storage Manager host software has to be updated to V10.60 to manage a
DS5000 storage subsystem with firmware V7.60. You must update the SM host software
before performing the firmware upgrade.
Older storage subsystems running CFW 5.x are no longer manageable with Storage
Manager Version 10.60.
