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

DescriptionOption
disable_reallocation| disable_relocation : Relocation of LDEV (V-VOL for Smart Tiers/Smart
Tiers Z) disabled
discard_zero_page: Discarding 0 page of LDEV(V-VOL) for Thin Provisioning, Thin
Provisioning Z, or Smart Tiers, and /Smart Tiers Z.
enable_relocation_policy <policy_id>: Enables the LDEV relocation for Smart Tiers and sets
the level or customized policy of the Tier to be used for the relocation by Policy ID.
<policy_id>:
• all: Uses all tiers in the pool.
• 1-5: Specifies the level of the tier for use.
• 6-31: Specifies the customized policy of the tier for use.
new_page_allocation: Sets the Tier when new page is allocated to the LDEV for Smart Tiers
(V-VOL). The value is one of high/middle/low.
For example:
• -status nml
Specifies the LDEV nickname (maximum 32 characters).-ldev_name <ldev
naming>
Specifies the MP blade ID (0-7).-mp_blade_id <mp#>
Changing MP blade ID should be executed during off-peak hours of I/O loading. Do not
change the MP blade ID during initial copying of Continuous Access Synchronous, Business
Copy, or Continuous Access Journal (on-peak hours of I/O loading).
To change the MP blade ID again for the same LDEV, wait for more than 30 minutes after
changing the MP blade ID. For example:
-mp_blade_id 2
When you change the MP blade ID where the LDEV is allocated, both before and after the
changing should be executed during as off-peak hours for the rate of write pending data
of the MP blade as possible. It recommends to execute when the rate of write pending data
of the all CLPR is less than 50%.
Do not change the MP blade ID in regard to a lot of LDEVs at the same time. The number
of LDEVs and I/O workload for which you can change the MP blade ID at the same time
is lower than 10% of the total number of LDEVs where the same MP blade ID is allocated
as a guideline.
Specifies SSID (hexadecimal number).-ssid <value>
When specifying SSID, specify not only unallocated SSID but also LDEV ID. In this case,
LDEV ID must be ID for the undefined LDEV in the area where SSID is not allocated. For
example:
-ssid 0x1234 -ldev_id 200
Note: This option is for enterprise storage systems.
Configures command device attribute.-command_device {y | n}
[Security value]
y: Command device attribute enabled.
n: Command device attribute disabled.
Specifies the value of command device security (0-7).
You can specify 0-7 to Security value as the command device security setting:
• 0: Security: OFF, User authentication: OFF, Group information acquisition: OFF
• 1: Security: OFF, User authentication: OFF, Group information acquisition: ON
• 2: Security: OFF, User authentication: ON, Group information acquisition: OFF
• 3: Security: OFF, User authentication: ON, Group information acquisition: ON
• 4: Security: ON, User authentication: OFF, Group information acquisition: OFF
• 5: Security: ON, User authentication: OFF, Group information acquisition: ON
