Make settings so that the system volume can operate normally even if the SCSI host ID of the disk constituting the system volume is changed.
Note
If you do not make this setting, the system may not be able to start when the SCSI host ID is changed due to patch application or hardware failure.
Information
SCSI host ID may be changed in the following cases:
When an initial RAM disk (initrd) is re-created by patch application
When HBA (SCSI card) fails
When PCI slot fails
With 4.3A10 or later, this setting is not required because the system volume is operated normally even if the SCSI host ID of the disk constituting the system volume is changed.
Apply the patch T001689QP-11 or later and T001963QP-11 or later.

For details on the application method, see the Update Information Files.
