High Availability Monitors Version A.03.20 Release Notes

8 Chapter1

Compatibility Information and Installation Requirements

Requirements for HA Disk Monitor Users:

There are two cases where the HA Disk Monitor has software

requirements:

• NIO Bus: To use the HA Disk Monitor with disks connected by an

NIO bus, you mustconﬁgure the SCSI pass-thru driver, spt0, into the

kernel.

— For HP-UX 10.20, install patch PHKL_13044 to add SCSI

pass-thru driver support. Add spt0 to the /stand/system ﬁle,

rebuild the kernel, and reboot.

— For HP-UX 11.0, add spt0 to the /stand/system ﬁle, rebuild the

kernel, and reboot. (The SCSI passthrough driver is already part

of the 11.0 operating system.)

• Fibre Channel: To use the HA Disk Monitor with disks connected by

ﬁbre channel, you must already have the SCSI passthrough driver

installed, as described in NIO Bus, above. Then, follow the directions

below:

— For HP-UX 10.20, install Fibre Channel Mass Storage Driver

product J3630BA, and any recommended patches.

— For HP-UX 11.0, install patch PHSS_18232, or the patch that

supersedes it, to get the latest ﬁbre channel driver.
