I'm quite new to true copy/shadow copy configurations, I have inherited some hpux servers configured with raidmanager and using truecopy and shadow copy, and I quite can't make sense of the current state they are in:
I'm using this variables, true copy is horcm instance 4, shadow copy on instance 0 and 1:
for the truecopy, I have some groups in this state:
local:/root> pairdisplay -g RES -fcx
Group PairVol(L/R) (Port#,TID, LU-M) ,Seq#,LDEV#.P/S,Status, % ,P-LDEV# M
RES1 vg001_res_1(L) (CL7-A-2, 0, 6-0 )337 91c.P-VOL PSUS, 94 600 W
RES1 vg001_res_1(R) (CL7-A-1, 0, 6-0 )338 91c.SMPL ----,----- ----- -
What I understand is that true copy isn't synchronizing because the remote lun 09:1c in box 338 is in simplex stare, andthe P-vol is in psus state because it has a shad how copy from source lun 09:1c to dest lun 06:00.
Is this correct??
I also have another state:
RES2 vg004_1(L) (CL7-A-2, 3, 0-0 )337 c3d.P-VOL PSUS, 99 b31 W
RES2 vg004_1(R) (CL7-A-1, 3, 0-0 )338 c3d.P-VOL PSUS, 99 b31 W
I don't now what to make out of this one..., looks like both boxes have a shadow configured, but is true copy in sync ??.
To me it looks like they left true copy out of sync, and the replication not working, does it look like it?.
