and I/O block transfer size:

Problems during installation
This section describes how to troubleshoot the most common problems encountered during software
installation.
To troubleshoot the problems encountered during installation, complete the following steps:
1. In a Microsoft environment, uninstall any previous version of the multipath software rst.
2. Ensure that the rmware is upgraded for all HBAs and both the MSA500 G2 controllers, if
installed.
3. Ensure that the hardware installation meets the Minimum requirements.
4. Ensure that the SCSI cabling matches one of the Supported four-node congurations.
5. Ensure that the HBA is functioning properly. See the appropriate server and HBA documentation.
If the HBA has failed, see HBA failure.
6. Ensure that the SCSI cables are functioning properly. If a SCSI cable fails, see Cable failure.
7. Ensure that you followed operating system-specic instructions:
If the server has a Red Hat operating system, ensure that the active kernel is edited properly.
If the server has a Microsoft operating system, ensure that the SCSI cable from the redundant
HBA is disconnected before Smart Array Multipath software installation.
IMPORTANT:
After establishing a redundant conguration and adding a logical volume, use Windows Disk
Manager to detect the new volume.
If these steps do not solve the installation problem, contact an authorized reseller.
