HP Application Recovery Manager software A.06.10 Administrator's guide (March 2008)

ZDB_BACKUP_VG_EXIST: On HP-UX platform, for systems configured with multiple
HBAs and connections to a disk array, the alternate paths solution performs dynamic
load balancing. By default, during preparation for backup and restore, Application
Recovery Manager creates a volume group with the disk on the first HBA as the
primary path.
To disable volume group autoconfiguration on the backup host and load balance
the data across multiple paths manually, set this variable to 1. The existing backup
volume group will be used in the next backup or restore session.
NOTE:
If this variable is set, volume groups are not removed from /etc/lvmtab on the backup
system after each backup. For more information, see “Backup options” on page 75.
Default: 0.
OB2AUTOPATH_BALANCING_POLICY: Specifies the HP StorageWorks AutoPath load
balancing policy used.
AutoPath provides enhanced data availability for systems configured with multiple
host adapters and connections to a disk array. When several alternate paths are
available, AutoPath dynamically balances data load between the alternate paths to
achieve optimum performance.
Possible values are:
• 0 [none] – No policy
• 1 [RR] – Round Robin policy (default)
• 2 [SQL] – Shortest Queue Length policy
• 3 [SST] – Shortest Service Time policy
For more information, see the AutoPath documentation.
SSEA_SPLIT_REPORT_RATE: During the split, XP Agent checks the status of mirrored
disks in intervals determined by SSEA_SPLIT_SLEEP_TIME.
SSEA_SPLIT_REPORT_RATE determines the frequency of displaying the mirrored
disks’ status to the Application Recovery Manager Monitor. For example, if
SSEA_SPLIT_SLEEP_TIME is 2 seconds and SSEA_SPLIT_REPORT_RATE is 5,
the status is displayed for every fifth check (every 10 seconds).
Default: 5.
SSEA_SPLIT_SLEEP_TIME: During the split, XP Agent checks the mirrored disks’ status.
SSEA_SPLIT_SLEEP_TIME determines the time interval between the status checks.
