4.21.1 Specifying the SLPR Protection Facility
When you want to access certain SLPRs on a single Host, use the CCI protection facility so
that the Host can access multiple SLPRs through a single command device. The following
outline reviews the setup tasks for the SLPR protection facility.
1. Setting SLPR on the command device: The command device has a SLPR number and an
associated bitmap so you can set multiple SLPRs. You accomplish this by sharing a
command device (using ports connected to different SLPRs) by setting the command
device through SLPR#0 (called Storage Administrator) on the Web console or SVP.
For example, if the command device will be shared with the port on SLPR#1 and SLPR#2,
then the command device will automatically set the bitmap corresponding to SLPR#1 and
SLPR#2.
2. Testing SLPR: CCI verifies whether or not the command device can access a target
within SLPR. So, if the command device belongs to SLPR#0, or CCI has no SLPR function,
then the SLPR protection is ignored.
However, if the command device will be shared with the port on SLPR#1 and SLPR#2, CCI
allows you to operate the volume on SLPR#1 and SLPR#2.
3. Rejecting commands: If access is denied on the specified port (or target volume), CCI
rejects the following commands and outputs an error code, EX_ESPERM:
–
Horctakeover, Paircurchk, Paircreate, Pairsplit, Pairresync, Pairvolchk, Pairevtwait,
Pairsyncwait
–
raidscan (except “-find verify”, “-find inst”), raidar, pairdisplay
–
raidvchkset, raidvchkscan (except “-v jnl”), raidvchkdsp
[EX_ESPERM] Permission denied with the SLPR
[Cause ] : A specified command device does not have a permission to access other
SLPR.
[Action] : Please make the SLPR so that the target port and the command device
belongs to the same SLPR.
