HP XP P9000 RAID Manager Reference Guide (T1610-96061, January 2014)

DescriptionOption
to 255 seconds. If this option is not specified, then '90' seconds is set as default. For Continuous
Access Journal, o-time can be specified from 1 to 600 seconds. If this option is not specified,
then '60' seconds is set as default. If 'o-time=0' is specified, the inflow of Write I/O becomes
invalid. If Sidefile quantity is over limit of Sidefile Area then host side Write I/O is waited for
enough space of Sidefile when storing next new write data until this timeout value (1 second to
255(600) seconds). Default timeout value are 90(60)seconds. If the timeout happens with this
waiting state then pair state is changed from 'PAIR' to 'PSUS' state of sidefile(Journal) Full, and
its host side Write I/O is continued and Writing data is managed by BITMAP mode. Therefore
o-time timeout value should have less a low value than I/O timeout value of the host system
[c-time]: (Applicable for only Continuous Access Synchronous Async) This option is used when
setting 'Copy Pending timer' to the specified CT group. c-time can be specified from 1 to 15
minutes. If this option is not specified, then this value is set as below.
• If CT group is created, then sets 5 minutes as default. If not, it is not changed.
[r-time]: (Applicable for only Continuous Access Synchronous Async) This option is used when
specifying 'RCU Ready timer' to the specified CT group. r-time can be specified from 1 to 10
minutes. If this option is not specified, then it is not changed.
Note:
• These options will also be able to set, if all volumes of CT group is suspended.
• The propagation and persistence of these parameters are as follows.
For Continuous Access Synchronous Async, these parameters are also forwarded to SVOL side
with pairresync command, and are used when SVOL is changed to PVOL. These parameters
are maintained until the pair-volumes are changed to SMPL.
For Continuous Access Journal, these parameters are maintained on each journal, therefore it
must be set for PVOL and SVOL. For example, to change 30 seconds for PVOL:
• pairsplit -g Cnt Ac-J
• pairresync -g Cnt Ac-J -cto 30
For changing a journal of SVOL side, the above operation must be issued after changing from
SVOL to PVOL. These parameters are maintained until the journal are broken.

-f[g] <fence>
[CTGID]
-f[g] <fence> [CTGID] (Continuous Access Synchronous only): This option is used to change
from existing Continuous Access Synchronous Sync volumes to Continuous Access Synchronous
Sync CTG without deleting paired-volume. It is possible to change the option (fence level) and
the volume attribute as shown below. This option is valid without '-swaps' or '-swapp' option.
